A Transparent Antipeep Piezoelectric Nanogenerator to Harvest Tapping Energy on Screen

Aligning PbZr(0.52)Ti(0.48)O3 (PZT) nanowires in polydimethylsiloxane introduces dielectrophoresis, improving the electromechanical properties of nanogenerators, and the light transmittance of composite films. A novel transparent and antipeep piezoelectric nanogenerator is developed that can be used for harvesting the energy from the light tapping of a finger on a cell phone, with an output current of 0.8 nA.
