The effect of O2 plasma treatment on surface energy, topography and chemistry the negative photoresist epoxy novolak SU-8 was investigated by contact angle goniometry, atomic force microscopy (AFM) x-ray photoelectron spectroscopy (XPS). Directly after treatment, surfaces were completely wetted water with a between below 5°. free energy can be increased significantly depending dose. remained hydrophilic for several months showing moderate hydrophobic recovery. treated showed formation...
Resistively switching memory cells (ReRAM) are strong contenders for next-generation non-volatile random access memories. In this paper, we present ReRAM on flexible substrates consisting of Ag/spin-on-glass/PEDOT:PSS (poly(3,4-ethylenedioxythiophene) polystyrene sulfonate). The complete cell is fabricated using a standard inkjet printer without additional process steps. Investigations the spin-on-glass insulating layer showed that low sintering temperatures sufficient good behavior,...
Abstract Wetting properties and surface roughness of SU‐8 can be modified by wet chemical plasma processes. These processes result in an enhanced wettability that attributed to increase CO COO groups at the surface. Wet etching with ceric ammonium nitrate (CAN) rendered hydrophilic. However, it also led accumulation cerium species on surface, which may interfere biochemical reactions device. Surface activation could achieved a low‐temperature atmospheric argon plasma, left smooth Treatment...
Abstract In recent years, photoacoustic generators based on multiwalled carbon nanotubes (MWCNT) and polydimethylsiloxane (PDMS) are manufactured in a variety of ways, which influences the properties with respect to frequency bandwidth, sound wave pressure, robustness, reproducibility. Due high optical absorption MWCNTs thermal expansion coefficient PDMS, this combination is ideally suited for use as generator. This study presents novel method produce long‐term stable MWCNT PDMS inks...
Printed and flexible sensors are in the focus of recent efforts to establish advantages low-cost manufacturing techniques such as screen printing or inkjet for printed electronical applications. Devices based on conductive carbon nanotube (CNT) networks within polymeric matrices polydimethylsiloxane (PDMS) already exceeding mere technological demonstrations. Therefore, we investigate application-oriented behaviour fully inkjet-printed CNT/PDMS strain under different conditions short-...
Resistive Random Access Memory (ReRAM) is a highly promising technology for various future memory applications. In this work, spin-on-glass (SOG) and WO3 nanoparticles are used as an insulating layer completely inkjet-printed ReRAM cells. The direct comparison shows that the difference in switching parameters can be to serve different device requirements While local filament formation with conductive atomic force microscopy confirms same mechanism both compounds, current–voltage...
The combination of printed electronic devices has a pivotal role in establishing intelligent designs fields such as smart labels for logistics or miniaturized health monitoring. Research to date tended focus on individually components rather than their integration. switching behaviour inkjet-printed, resistively memory cells driven by screen-printed Zn-MnO2 microbattery, is investigated. Both have shared Ag electrode that low-cost, flexible, and transparent polyethylenterephthalat (PET)...
The fabrication and characterization of resistive memory cells based on a silver/silicon oxide stack with printed polymer electrode is described.

Together the possibility multi‐level data storage even substrates, potential for power, high density, cheap demonstrated. Memristor its current–voltage characteristic.
Several factors influence the accuracy of results when using Split Hopkinson bar. These include longitudinal wave dispersion, and impedance mismatch bars with specimens. In this paper, we discuss our approach to choosing specimen dimensions based on their impedance, thereby improving transmitted stress signal-to-noise ratio. We also show that, by implementing numerical procedures, precise alignment strain-pulses is facilitated that essential for proper dispersion correction.
