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 (R-F-SPEs), completely wireless paper-based electronic devices insensitive to moisture, liquid stains, and dust. R-F-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. R-F-SPEs are lightweight, inexpensive to print (<$0.25 per device), and capable of generating power densities up to 300 mu W/cm(2). Additionally, R-F-SPEs are flexible and exhibit excellent stability upon folding (0.3 mm radius of curvature). The simple printing process and relative low cost of R-F-SPEs enable the large-scale production of selfpowered paper-based electronics towards the ubiquitous integration of human-machine interfaces.
