Abstract
Abstract The fabrication of multifunctional electronic devices on ubiquitous paper substrates is gaining considerable attention due to their low cost, environmental friendliness, light weight, and flexibility. Unfortunately, the development of paper-based electronics is subject to significant challenges, such as rapid degradation with moisture, battery dependence, and limited compatibility with existing mass production technologies. This work describes omniphobic, self-powered paper-based electronics (RF-SPEs), completely wireless paper-based electronic devices insensitive to moisture, liquid stains, and dust. RF-SPEs can be rapidly fabricated through the sequential spray-deposition of alkylated organosilanes, conductive nanoparticles, polytetrafluoroethylene (strong electron affinity), and ethyl cellulose (weak electron affinity) over the surface of cellulose paper. RF-SPEs are lightweight, inexpensive to print (
