Flexible Pyroelectric Nanogenerators using a Composite Structure of Lead-Free KNbO3 Nanowires

Authors


Abstract

Pyroelectric nanogenerators fabricated using a lead-free KNbO3 nanowire-PDMS polymer composite are reported for the first time. The voltage/current output of the nanogenerators can be controlled by electric fields and enhanced by increasing the rate of change in temperature. The fabricated nanogenerators can be used to harvest energy from sunlight illumination and have potential applications in self-powered nanodevices and nanosystems.
