A micro-patterned transient UV photodetector enabled by solvent-free microfabrication.

ABSTRACT: Transient electronics, which can be controllably broken down with zero environmental impact, hold significant potential in implantable devices, hardware security, and disposable sensors. While miniaturization is essential for enhancing device performance, increasing integration density, and enabling new applications, degradable materials often face challenges with conventional microfabrication processes like lithography due to their sensitivity to heat and solvents. In this paper, we present a UV photodetector (PD) with micro-scale patterning, fabricated using a novel solvent-free material patterning method. The PD, consisting of molybdenum (Mo) as the electrode, zinc oxide (ZnO) as the photoactive material, and polyvinyl alcohol (PVA) as the substrate, can be dissolved in deionized (DI) w
