Application of PVP/SbSI Nanocomposite for Energy Generation and Dynamic Pressure Sensing

Article Preview

Abstract:

This work introduces a novel PVP/SbSI nanocomposite that exhibits a significant piezoelectric response to variations in air pressure. Demonstrated functionalities include its use as a pressure sensor and nanogenerator under dynamic conditions. For a sandwich-type configuration with nanofibers oriented perpendicularly to the electrodes, the sample generated a peak voltage of about 2.1 V, a charge generation rate of 97.1 pC/N, a sensitivity of about 0.23 mV/bar, a surface power density of over 12 µW/cm², and an energy output of 3.5 nJ under a differential pressure of 17 bar. The study also examines the agreement among various methods of efficiency evaluation.
