A single crystal Pb(Mg1/3Nb2/3)O3-Pb(Zr,Ti)O3 (PMN-PZT) energy harvester is demonstrated by solid-state crystal growth and an optimized delamination process. The flexible harvester generates an output voltage of 100 V and a current of 20 µA. The advanced reconfigurable rectifying circuit enhanced conversion efficiency of the PMN-PZT harvester is compared to conventional rectifier. Finally, a self-powered military boot is fabricated using the harvester as a demonstration of use in operating consumer electronics.
