Flexible electrodes have significant potential in fields such as healthcare and neuroscience, as they enable comprehensive recording and analysis of human electrical signals, providing deeper insights into physiological conditions and the state of internal organs and tissues [1, 2]. However, commercial Ag/AgCl wet electrodes face issues such as dehydration,poor comfort, and insufficient mechanical strength, while other types of electrodes, like dry and semi-dry electrodes,also have their own limitations, including the higher contact impedance.

This work presents the development of InSnZnO (ITZO) three-dimensional (3D) channel dual-gate thin-film transistors (DGTFTs) prepared by magnetron sputtering. The employment of an n-octyltriethoxysilane protection layer, prepared via liquid-phase self-assembly, effectively mitigates plasma-induced damage to the ITZO channel layer during top gate dielectric sputtering. Moreover, the high-k ZrO2 top gate dielectric and 3D channel structure endow the ITZO DGTFTs with excellent transistor performance, high electrical stability, and flexible mechanical reliability. These attributes include a low threshold voltage of 0.2 V, a high mobility of 41.7 cm2V-1s-1, and a competitive top gate coupling coefficient of -2.24. Finally, the ultra-high top-gate voltage coupling effect allows the ITZO DGTFT-based wearable pulse sensor accurately recognizes pulse waveforms from various parts of the body, including the temples, and infers blood pressure changes. © 2024 IEEE.

In this work, a combined system including FLC high-speed polarization rotator, liquid crystal polymerizable polarization grating, FLC switchable Dammann Grating is proposed to form tunable diffractive spot matrices and acquire depth information. By adjusting electric field, the grating can be switched between diffractive state showing 4 by 4 optical spots arrays in two areas and non-diffractive state, respectively. At a low driving voltage of 5V, our approach renders the gratings electrically tunable with a fast response time of 50μs, which has the potential for LiDAR applications. © 2022, John Wiley and Sons Inc.
