Pyroelectric nanogenerators fabricated using a lead‐free KNbO 3 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.
