[Bibtex]@article{10516288, abstract = {Advancements in materials and technologies have enabled thin-film electronics to be directly developed on previously unsuitable substrates. This article explores the fabrication of two thin-film temperature sensors, thermistors, and resistance temperature detectors (RTDs), using stone-based substrates, including marble, brick, stone paper, and Limex paper. The thermistors and RTDs were fabricated utilizing Cu/InGaZnO and Zn, applying the sputtering deposition technique. The sensor’s performance was analyzed based on two different heating methodologies: one using a hotplate, and the other using localized heating from above. The sensors’ performance was characterized within a temperature range of $25~^{\circ }$ C– $80~^{\circ }$ C. While the marble thermistor demonstrated the highest sensitivity among all thermistors at −11.54% $^{\circ }\text {C}^{-1}$ , the stone paper RTD similarly showed the highest sensitivity among all RTDs at 0.064% $^{\circ }\text {C}^{-1}$ . The localized heating methodology on top of RTDs resulted in the stone paper and Limex showing negligible hysteresis. Moreover, the sensors demonstrated stable behavior in the multiple reliability tests. Furthermore, Zn-based RTDs were dissolvable in less than 36 h. The outcomes show that stone-based materials are promising natural eco-friendly substrates for temperature sensors leading to less hazardous electronic waste.}, added-at = {2024-12-18T16:09:27.000+0100}, author = {Saeedzadeh Khaanghah, Niloofar and Oliveira, Hugo de Souza and Krik, Soufiane and Carrasco-Pena, Alejandro and Cantarella, Giuseppe and Haller, Michael and Rapagnani, Nicholas and Bezooijen, Aart van and Nippa, Michael and Münzenrieder, Niko}, biburl = {https://www.bibsonomy.org/bibtex/2532c5ae649dea6ba13bd7989ee6044b1/nikomu}, doi = {10.1109/JSEN.2024.3393113}, interhash = {1a27cbb10426427978016c16d163a3fc}, intrahash = {532c5ae649dea6ba13bd7989ee6044b1}, issn = {1558-1748}, journal = {IEEE Sensors Journal}, keywords = {myown}, month = dec, number = 24, pages = {40179-40187}, timestamp = {2024-12-18T16:10:38.000+0100}, title = {Application of Stone-Derived Substrates in Thin-Film Temperature Sensing}, volume = 24, year = 2024 } - A.

[Bibtex]@inproceedings{10719906, abstract = {Magnetically guided untethered devices are used in a variety of medical applications. These devices are typically powered by onboard battery units. Hydrogen fuel cells (FC) are a promising alternative power source for such small-scale devices since they rely on a sustainable fuels which produce electric power from the redox reaction of hydrogen and oxygen across a proton exchange membrane (PEM). Understanding the impact of decreasing the active electrode area in FCs is crucial for deploying FCs in untethered devices and gaining insights into the challenges of downscaling the devices. This paper investigates the performance of PEM FCs (PEMFCs) when their active area is reduced, and when the FC is supplied with reactants at different flow rates from a PEM electrolyzer. PEMFCs with three active electrode areas, 3.5 × 3.5 cm2, 2.7×2.7 cm2, and 1.6×1.6 cm2were designed, fabricated, and characterised. Maximum fuel cell output powers of 0.3 W, 0.09 W, and 0.03 W (maximum power densities of 0.025 W/cm2, 0.012 W/cm2, and 0.013 W/cm2) corresponding to the three aforementioned areas were achieved. Mathematical modeling of the PEMFC simulated the FC response, providing insights into the activation kinetics of the fuel cell. The smallest PEMFC with an active area of 1.6 × 1.6 cm2was used to power an inductor coil (rated 130 mA, 150 mH, 8 Ω).

To address this global issue, we implemented thin-film resistance temperature detectors (RTDs) using green sensing metals, such as Mg, Mo, and Zn, and poly-ether ether ketone (PEEK), as a biocompatible, flexible, and thermally resistant substrate. The environmentally friendly RTDs were characterized in a range of temperature, from 25 °C to 70 °C, showing consistent response and average sensitivities of $1.1\times 10^{-1}$ %/°C, $7\times 10^{-2}$ %/°C, and $5.8\times 10^{-2}$ %/°C for Mg, Mo, and Zn, respectively. At a constant temperature 25 °C, the effect of humidity variation from 10% to 90% on the resistance of the sensors was observed to be $2.0\times 10^{-5}$ %/relative humidity (RH), $3.4\times 10^{-2}$ %/RH, and $5\times 10^{-3}$ %/RH, respectively, for Mg, Mo, and Zn RTDs. Furthermore, the sensor’s response to mechanical strain was evaluated by bending the devices down to a 10-mm bending radius. In addition, the dissolution of the green RTDs in water allows the reusability of the substrate for a new fabrication batch, minimizing the amount of electronics waste generated.

This work presents the use of a single InGaZnO double gate TFT able to modulate the amplitude and mix the frequencies of AC signals with frequencies up to $\approx 10\text{kHz}$. When used as a modulator, the design with two independent asymmetric gates allows the simultaneous application of a high-frequency carrier and a low-frequency modulation signal.

Measurements also show that in most devices the stress-induced shift can be fully recovered by applying a $VGs{=}-2\mathrm{V}$ for 1000 s as a result of releasing charges previously trapped during stress.}, added-at = {2024-12-18T08:55:39.000+0100}, author = {De Rosis, Domenico and Vatalaro, Massimo and Maccaronio, Vincenzo and Crupi, Felice and Münzenrieder, Niko and Catania, Federica and Corsino, Dianne and Cantarella, Giuseppe and Petti, Luisa and De Rose, Raffaele}, biburl = {https://www.bibsonomy.org/bibtex/25dea0f8cd21f8f717ba8de58945dc810/nikomu}, booktitle = {2024 IEEE International Flexible Electronics Technology Conference (IFETC)}, description = {Threshold Voltage Instability in Flexible Bottom-Gate Al2O3/IGZO TFTs | IEEE Conference Publication | IEEE Xplore}, doi = {10.1109/IFETC61155.2024.10771861}, interhash = {1b919d25d9992c74303902426be8e5aa}, intrahash = {5dea0f8cd21f8f717ba8de58945dc810}, keywords = {myown}, month = {Sep.}, pages = {1-3}, timestamp = {2024-12-18T08:55:39.000+0100}, title = {Threshold Voltage Instability in Flexible Bottom-Gate Al2O3/IGZO TFTs}, year = 2024 } - F.

Different technologies, including devices based on organic semiconductors and conventional silicon, are used to develop such wearable systems, however, devices made from novel oxide-based semiconductors currently have one of the best changes to result in electronic systems with sufficient electrical performance on flexible and large-area substrates. Yet, these exciting possibilities come at a price. If all the objects and surfaces around us are equipped with electronic sensor systems, these objects themselves transform into electronic devices, which in turn would massively increase the amount of electronic waste at the end of their lifetime. The same is true for plastic waste as currently most unobtrusive electronics are fabricated on polymer substrates. Furthermore, electronics that are operated near the human body must be safe and biocompatible. The perfect solution for these problems would be to fabricate electronics using environmentally friendly materials and processes, and to guarantee that the electronic components, after fulfilling their intended task, dissolve into their basic constituents, which are then entirely passive or safely absorbed into the nutrient cycle of our environment.

The hinge utilizes the shape memory effect (SME), thanks to the use of a shape memory alloy (SMA). First SMA wires based on Nickel-Titanium are embedded into an Ecoflex polymeric material and subsequently solidified. The bending of the hinge is induced by a thermal stimulus provided by a silver-based heater printed on a $10\mu m$ thick Polyether ether ketone (PEEK) substrate and embedded on top of the SMA structure. Heater powering is achieved via commercially available solar cells. Upon heating, the hinge transforms from a flat horizontal configuration to a curved bent one with approximately 45° bending angle on both sides of the hinge. In this work, we first describe the working principle of the hinge, to then show how the hinge is designed and prototyped, along with the realization of the proof-of-concept-device. Finally, laboratory testing of the autonomous hinge prototype is shown to investigate its motion and energy consumption performance. Upon reducing the temperature of the SMA wires by switching off the heater, the hinge returns to its original position with a 10° bending angle.

Furthermore, the integrated side-by-side fabrication enables the electrical comparison of both types of TFTs excluding external factors.

The unique approach we followed was to realise from the ground up the sensing elements, their integration into a textile, and the associated data processing.

First, simulation models are used to guide the fabrication of operational amplifiers and logic circuits on flexible polyimide foil, using an additional third metal layer for the interconnections. Thanks to the reduced parasitic resistances and capacitances, the resulting circuits have yielded improved electrical performances with respect to a two-metals architecture.

Due to the capacitive nature of the technique, the terminals of the voltage source under test can be either exposed to the sensing element or insulated. As well as non-contact measurements of DC potentials, this technique can be used to image the electrostatic charge distribution on insulating materials.

Here, five ways to electrically connect soft Ecoflex based strain sensors are evaluated. The results show that a filament cable exhibits the most stable behaviour under cyclic loading of the contacts, while using a multi strand cable or a copper mesh results in lower contact resistance. In addition, loading forces from 0.27 N to 6.92 N are supported. Finally, stretchable piezoresistive strain sensors are fabricated using the 5 different contact methods.

The method relies on measuring the electric potential of an AC voltage source using a single capacitive electrometer. Simultaneously, the distance from the AC source is measured using time-of-flight sensors. By combining the data from both sensors, AC voltages can be measured accurately without the need for any galvanic contact. The system is packaged in a handheld battery powered form factor. Measurements of voltages between 25 VRMS and 250 VRMS and distances from 25 mm to 600 mm demonstrated accuracy within 4%. Furthermore, frequencies between 5 Hz to 500 Hz were measured with 10 mHz of resolution.

Solution-processed lead halide perovskite offers numerous distinctive characteristics, such as pure emission color, tunable bandgaps, and low fabrication cost. In this paper, green perovskite LEDs (PeLEDs) are fabricated on 50-μm thick polyimide substrates. Using colloidal 2-D formamidinium lead bromide perovskite emitter, the PeLEDs show a high current efficiency (ηCE) of 5.3 cd A-1 with a peak emission at 529 ± 1 nm and a narrow width of 22.8 nm. The resultant green emission shows color saturation > 95%, in the Rec. 2020 standard gamut area. To demonstrate mechanical flexibility, the device functionality is tested by dynamic bending experiments down to 10 mm for up to 5000 cycles, resulting in device lifetime over 36 h in a glove box and a drop of ηCE and external quantum efficiency (ïext) as low as 15% and 18%, respectively.

This model was used to evaluate a new concept, namely, the active compensation of strain-induced performance variations in pixel driving circuits for bendable active matrix arrays. The designed circuits can compensate the mobility and threshold voltage shifts in IGZO TFTs induced by bending. In a single TFT, a drain current of 1 mA varies by 83 μA per percent of mechanical strain. The most effective compensationcircuit design, comprising one additional TFT and two resistors, reduces the driving current variation to 1.1 μA per percent of strain.

[Bibtex]@article{8411327, abstract = {In this paper, the low-temperature (≤150 °C) fabrication and characterization of flexible indium-gallium-zinc-oxide (IGZO) top-gate thin-film transistors (TFTs) with channel lengths down to 280 nm is presented. Such extremely short channel lengths in flexible IGZO TFTs were realized with a novel manufacturing process combining two-photon direct laser writing (DLW) photolithography with Ti/Au/Ti source/drain e-beam evaporation and liftoff. The resulting flexible IGZO TFTs exhibit a saturation field-effect mobility of 1.1 cm2 · V-1 · s-1 and a threshold voltage of 3 V. Thanks to the short channel lengths (280 nm) and the small gate to source/drain overlap (5.2 μm), the TFTs yield a transit frequency of 80 MHz (at 8.5-V gate-source voltage) extracted from the measured S-parameters. Furthermore, the devices are fully functional when wrapped around a cylindrical rod with 6-mm radius, corresponding to 0.4% tensile strain in the TFT channel. These results demonstrate a new methodology to realize entirely flexible nanostructures and prove its suitability for the fabrication of short-channel transistors on polymer substrates for future wearable communication electronics.}, added-at = {2023-05-22T12:07:33.000+0200}, author = {Petti, Luisa and Greco, Emanuel and Cantarella, Giuseppe and Münzenrieder, Niko and Vogt, Christian and Tröster, Gerhard}, biburl = {https://www.bibsonomy.org/bibtex/258c575cdc4e65c734d489dfd9efb7366/nikomu}, doi = {10.1109/TED.2018.2851926}, interhash = {a55dd8a33b1702cffc731467ec851cdb}, intrahash = {58c575cdc4e65c734d489dfd9efb7366}, issn = {1557-9646}, journal = {IEEE Transactions on Electron Devices}, keywords = {myown}, month = {Sep.}, number = 9, pages = {3796-3802}, timestamp = {2023-05-22T12:07:33.000+0200}, title = {Flexible In–Ga–Zn–O Thin-Film Transistors With Sub-300-nm Channel Lengths Defined by Two-Photon Direct Laser Writing}, url = {https://ieeexplore.ieee.org/document/8411327/}, volume = 65, year = 2018 } - J.

For this reason, the impacts of high energetic electron irradiation with fluences up to 1012e-/cm2 and low operating temperatures down to 78 K, are investigated. This simulates 278 h in a Low Earth Orbit. The threshold voltage and mobility of transistors that were exposed to e- irradiation are found to shift by +0.09±0.05V and -0.6±0.5cm2V-1s-1. Subsequent low temperature exposure resulted in additional shifts of +0.38V and -5.95 cm2V-1s-1 for the same parameters.

On the basis of extensive device characterization, we introduce appropriate new equations and parameters that enable an accurate and efficient behavioral representation of a-IGZO TFTs. In this work, we address the modelling of short channel effects, the scalability for channel lengths from 5 µm to 50 µm, as well as the presence of process variation. Using this model, a Cherry-Hooper amplifier is designed, analyzed, implemented in a flexible a-IGZO TFT technology, and characterized. Finally, to validate the presented transistor model, we compare circuit simulations and measurements of the Cherry-Hooper amplifier circuit. The amplifier provides a voltage gain of 9.5 dB and has a GBW of 7.2 MHz from a supply voltage of 6 V. The simulation using our new compact transistor model resembles the measured characteristics very well.

A bilayer lift-off process is used to structure a spacing layer with a tilted sidewall and the drain contact on top of the source electrode. The resulting quasi-vertical profile ensures a good coverage of the successive device layers.

Once the fabrication is completed, the PDMS is detached from a silicon wafer used as carrier substrate. Due to the thermal mismatch between silicon and PDMS, the release results in a reduction of the PDMS area by 7.2%, which leads to the formation of out-of-plane wrinkles on the TFT surface. The reflattening of the wrinkles under tensile strain enables device functionality, while the TFTs are bent up to 2.3% strain.

Here, we present mechanically flexible amorphous InGaZnO (a-IGZO) memory thin-film transistors (TFTs) with a ferroelectric poly(vinylidene fluoride-trifluoroethylene) [P(VDF-TrFE)] gate insulator. Memory operation is demonstrated with a memory window of 3.2 V and a memory ON/OFF ratio of 1.5×106 (gate-source voltage sweep of ±6 V). The measured mobility of 8 cm2 V-1s-1 and the ON/OFF current ratio of 107 are comparable with the values for reference TFTs fabricated on the same substrate. To use memory TFTs in flexible applications, it is crucial to understand their behavior under mechanical strain. Flexible memory and reference TFTs are characterized under bending radii down to 5.5 mm, corresponding to tensile and compressive strain of ≈ ±0.6%. For both memory and reference TFTs, tensile strain causes negative threshold voltage shifts and increased drain currents, whereas compressive strain results in the opposite effects. However, memory TFTs, compared with reference TFTs, exhibit up to 8× larger threshold voltage shifts and 17× larger drain current variations. It is shown that the strain-dependent properties of a-IGZO can only explain the shifts observed in reference TFTs, whereas the variations in memory TFTs are mainly caused by the piezoelectric properties of P(VDF-TrFE).}, added-at = {2023-05-22T11:32:26.000+0200}, author = {Petti, Luisa and Münzenrieder, Niko and Salvatore, Giovanni A. and Zysset, Christoph and Kinkeldei, Thomas and Büthe, Lars and Tröster, Gerhard}, biburl = {https://www.bibsonomy.org/bibtex/2c38790d04c9f252d07e8ddc990f6e075/nikomu}, doi = {10.1109/TED.2014.2304307}, interhash = {497a2f713f377d05fb215d2dd61649bb}, intrahash = {c38790d04c9f252d07e8ddc990f6e075}, issn = {1557-9646}, journal = {IEEE Transactions on Electron Devices}, keywords = {myown}, month = {April}, number = 4, pages = {1085-1092}, timestamp = {2023-05-22T11:32:26.000+0200}, title = {Influence of Mechanical Bending on Flexible InGaZnO-Based Ferroelectric Memory TFTs}, url = {https://ieeexplore.ieee.org/document/6774450/}, volume = 61, year = 2014 } - G.

[Bibtex]@article{MUNZENRIEDER2013198, abstract = {In this paper, the concept of double gate transistors is applied to mechanically flexible amorphous indium–gallium–zinc-oxide (a-IGZO) thin film transistors (TFTs) fabricated on free standing plastic foil. Due to the temperature sensitivity of the plastic substrate, a-IGZO is a suitable semiconductor because it provides carrier mobilities around 10cm2/Vs when deposited at room temperature. Double gate TFTs with connected bottom and top gate are compared to bottom gate reference TFTs fabricated on the same substrate. Double gate a-IGZO TFTs exhibit a by 78% increased gate capacitance, a by 700mV higher threshold voltage, and therefore an up to 92% increased transconductance when characterized at the same gate voltage above threshold (over-bias voltage). The subthreshold swing and the on/off current ratios are improved as well, and reach excellent values of 69mV/dec and 2×109, respectively. The mechanical flexibility of double gate TFTs compared to bottom gate TTFs is investigated, and device operation is shown while the double gate TFT is exposed to tensile strain of 0.55%, induced by bending to a radius of 5mm.}, added-at = {2023-05-22T11:07:22.000+0200}, author = {Münzenrieder, Niko and Zysset, Christoph and Petti, Luisa and Kinkeldei, Thomas and Salvatore, Giovanni A. and Tröster, Gerhard}, biburl = {https://www.bibsonomy.org/bibtex/237cb78f41f3b5d8e5cd564b47681878f/nikomu}, description = {Flexible double gate a-IGZO TFT fabricated on free standing polyimide foil - ScienceDirect}, doi = {https://doi.org/10.1016/j.sse.2013.02.025}, interhash = {932f00a0b128982347a029694444ee8e}, intrahash = {37cb78f41f3b5d8e5cd564b47681878f}, issn = {0038-1101}, journal = {Solid-State Electronics}, keywords = {myown}, note = {Selected Papers from the ESSDERC 2012 Conference}, pages = {198-204}, timestamp = {2023-05-22T11:07:22.000+0200}, title = {Flexible double gate a-IGZO TFT fabricated on free standing polyimide foil}, url = {https://www.sciencedirect.com/science/article/pii/S0038110113000865}, volume = 84, year = 2013 } - G.

In addition, smart textiles offer potential in technical textiles: they comprise car and airplane interiors where lighting and emergency signaling are potential applications, in bandages for wound monitoring or automatically adjusting furniture in homes. The chapter starts with an introduction outlining the state-of-the-art smart-textile production. Then the processes for the fabrication of electronics on flexible plastic stripes, mechanical requirements due to the integration into woven textiles and the integration method of the flexible stripes into woven textiles are described. The feasibility of the technology is demonstrated with three prototypes: one prototype measures humidity and temperature, the second one has an integrated bus system and the last one is a textile integrated active matrix with light emitting diodes. At the end of the chapter, potentials of the technology are described to overcome issues related to smart textiles production, such as user acceptance, washability or large-scale production.}, added-at = {2023-05-22T10:59:12.000+0200}, author = {Zysset, C. and Kinkeldei, T. and Münzenrieder, N. and Tröster, G. and Cherenack, K.}, biburl = {https://www.bibsonomy.org/bibtex/209137931589a9496c567de3394c19986/nikomu}, booktitle = {Multidisciplinary Know-How for Smart-Textiles Developers}, description = {Fabrication technologies for the integration of thin-film electronics into smart textiles - ScienceDirect}, doi = {https://doi.org/10.1533/9780857093530.2.227}, editor = {Kirstein, Tünde}, interhash = {41b23633815033a74876635b75d1e30e}, intrahash = {09137931589a9496c567de3394c19986}, isbn = {978-0-85709-342-4}, keywords = {myown}, pages = {227-252}, publisher = {Woodhead Publishing}, series = {Woodhead Publishing Series in Textiles}, timestamp = {2023-05-22T11:00:06.000+0200}, title = {Fabrication technologies for the integration of thin-film electronics into smart textiles}, url = {https://www.sciencedirect.com/science/article/pii/B9780857093424500080}, year = 2013 } - C.

[Bibtex]@article{KINKELDEI201281, abstract = {Fabrication costs of gas sensors are decreasing due to the use of low cost flexible polymer substrates and solution based fabrication processes. This development creates new application possibilities for gas sensors and allows the installation into objects of our daily life, such as textiles. Challenges with the integration of electronic components on flexible substrates arise mainly due to strain introduced by bending the substrate. This plays an important role especially during weaving as strong mechanical forces bend flexible electronic devices to radii below 1mm. To demonstrate that it is feasible to integrate low cost gas sensors into a textile while preserving the functionality, we developed an electronic nose system for textile integration. The electronic nose consists of four carbon black/polymer gas sensors fabricated on a flexible polymer substrate. After fabrication the substrate was cut into yarn like strips and integrated into a textile to create a smart textile with gas sensing functionalities. We used this smart textile to detect different solvent vapors and classified them accordingly. It was possible to detect single solvents such as acetone until a minimal concentration of 50ppm. The influence of bending on sensors was studied, signal changes introduced by bending could be separated from changes due to solvent exposure. Bending of single strips to a radius below 1mm did not alter the sensor functionality. The presented work shows the feasibility of the process in combination with textile integration.}, added-at = {2023-05-22T10:47:04.000+0200}, author = {Kinkeldei, T. and Zysset, C. and Münzenrieder, N. and Tröster, G.}, biburl = {https://www.bibsonomy.org/bibtex/253303e85bfc802630e4a4620880db34d/nikomu}, description = {An electronic nose on flexible substrates integrated into a smart textile - ScienceDirect}, doi = {https://doi.org/10.1016/j.snb.2012.08.023}, interhash = {7dacf768c2a9ef23cdb4eddfa5dc8ef0}, intrahash = {53303e85bfc802630e4a4620880db34d}, issn = {0925-4005}, journal = {Sensors and Actuators B: Chemical}, keywords = {myown}, pages = {81-86}, timestamp = {2023-05-22T10:47:04.000+0200}, title = {An electronic nose on flexible substrates integrated into a smart textile}, url = {https://www.sciencedirect.com/science/article/pii/S0925400512008374}, volume = 174, year = 2012 }

[Bibtex]@article{munzenrieder2011testing, abstract = {Thin-film transistors (TFTs) fabricated on flexible plastic substrates are an integral part of future flexible large-area electronic devices like displays and smart textiles. Devices for such applications require stable electrical performance under electrical stress and also during applied mechanical stress induced by bending of the flexible substrate. Mechanical stress can be tensile or compressive strain depending on whether the TFT is located outside or inside of the bending plane. Especially the impact of compressive bending on TFT performance is hard to measure, because the device is covered with the substrate in this case. We present a method which allows us to continuously measure the electrical performance parameters of amorphous Indium-Gallium-Zinc Oxide (a-IGZO) based TFTs exposed to arbitrary compressive and tensile bending radii. To measure the influence of strain on a TFT it is attached and electrically connected to a flexible carrier foil, which afterwards is fastened to two plates in our bending tester. The bending radius can be adjusted by changing the distance between these plates. Thus it is possible to apply bending radii in the range between a totally flat substrate and ≈1 mm, corresponding to a strain of ≈3.5%. The tested bottom-gate TFTs are especially designed for use with our bending tester and fabricated on 50 μm thick flexible Kapton® E polyimide substrates. To show the different application areas of our bending method we characterized our TFTs while they are bent to different tensile and compressive bending radii. These measurements show that the field effect mobilities and threshold voltages of the tested a-IGZO TFTs are nearly, but not absolutely, stable under applied strain, compared to the initial values the mobilities shift by ≈3.5% in the tensile case and ≈−1.5% in the compressive one, at a bending radius of 8 mm. We also measured the influence of repeated bending (2500 cycles over ≈70 h), where a shift of the performance parameters can be observed, too. The saturation mobility of the flat device decreases by 4.5%, and the threshold voltage raises 0.1 V. These results show that it is possible to characterize the influence of different kinds of bending on flexible thin-film devices in a very reliable way with one experimental setup.}, added-at = {2023-05-22T10:40:47.000+0200}, author = {Münzenrieder, N.S and Cherenack, K.H and Tröster, G.}, biburl = {https://www.bibsonomy.org/bibtex/223d4bdf231a130390a80b184a1e6f865/nikomu}, description = {Testing of flexible InGaZnO-based thin-film transistors under mechanical strain | The European Physical Journal - Applied Physics | Cambridge Core}, doi = {DOI: 10.1051/epjap/2011100416}, interhash = {0f496c7caa1ead12c03d5ba43e527462}, intrahash = {23d4bdf231a130390a80b184a1e6f865}, issn = {12860042}, journal = {European Physical Journal-Applied Physics}, keywords = {myown}, number = 2, pages = {23904--}, publisher = {EDP Sciences}, timestamp = {2024-04-15T14:25:48.000+0200}, title = {Testing of flexible InGaZnO-based thin-film transistors under mechanical strain}, url = {https://www.cambridge.org/core/article/testing-of-flexible-ingaznobased-thinfilm-transistors-under-mechanical-strain/958EB7BA5FE2289FDD84E2331C4E7816}, volume = 55, year = 2011 } - C.
