文摘

ZnO nanoparticles etched porous electret P(VDF-HFP) film is spot lighted. Superior dielectric and ferroelectric properties without any poling are observed. It harvests 9 V output voltage with 4.7 μA current under 0.36 MPa stress. It shows superior power density and energy conversion efficiency of same stress. It also acts as self-powered wireless sensor for detecting tiny human activities.
