Abstract

Abstract: Spontaneous electric generation in ambient environment is attractive for revolutionary power supply systems. Herein, we report a moist-electric film generator (MEFG) that can simultaneously possess high flexibility, transparency and peculiarly self-healing ability derived from the rational combination of poly(4-styrensulfonic acid) with poly(vinyl alcohol). This flexible MEFG can be tailored and folded arbitrarily. A tiny piece of MEFG (2 mm 2 ) will produce a considerable voltage of 0.6 V and a power of about 7.9 μW cm −2 under natural moisture. Even being cut off, MEFG can heal spontaneously and revive the flexibility, transparence and electric power with 100% healing efficiency. The high accumulated power by serial connection of MEFGs can be supplied on demand to viably drive commercial electronics regardless of being bent or broken severely. The self-powered wearable watch and display bulb are successfully achieved on the basis of MEFGs, which demonstrates the promising applications for next-generation versatile power sources. Graphical abstract: A versatile moist-electric film generator (MEFG) endowed with transparent, self-healing, flexible and arbitrary tailorable characters is developed by the rational combination of poly(4-styrensulfonic acid) with poly(vinyl alcohol). Even being broken, MEFGs availably heal itself and revive the flexibility, transparence and electric power with 100% healing efficiency. Such MEFGs are viably integrated into self-powered, self-healing or display electronics.

This MEFG can revive electric power, flexibility and transparence with 100% healing efficiency after undergoing damage. MEFGs open up application in self-powered, self-healing, flexible wearable, and optically transparent electronics.
