Here micropatterned poly(vinylidenefluoride-co-trifluoroethylene) (P(VDF-TrFE)) films-based piezoelectric nanogenerators (PNGs) with high power-generating performance for highly sensitive self-powered pressure sensors are demonstrated. The microstructured P(VDF-TrFE)-based PNGs reveal nearly five times larger power output compared to a flat film-based PNG. The micropatterning of P(VDF-TrFE) polymer makes itself ultrasensitive in response to mechanical deformation. The application is demonstrated successfully as self-powered pressure sensors in which mechanical energy comes from water droplet and wind. The mechanism of the high performance is intensively discussed and illustrated in terms of strain developed in the flat and micropatterned P(VDF-TrFE) films. The impact derived from the patterning on the output performance is studied in term of effective pressure using COMSOL multiphysics software.
