Transparent, self-healing, arbitrary tailorable moist-electric film generator

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...
