摘要
Piezoelectric nanogenerators(PENGs)and triboelectric nanogenerators(TENGs)are representative technologies that can harvest mechanical energy.In general,piezoelectric/triboelectric hybrid generators can harvest considerable energy with a limited input;however,PENGs and TENGs entail different requirements for harvesting energy.Specifically,PENGs produce a large output when a large mechanical strain is applied,and TENGs require a large surface area to produce a high power.Therefore,it is necessary to develop an innovative strategy in terms of the structural design to satisfy the requirements of both PENGs and TENGs.In this study,we developed a triangulated cylinder origami-based piezoelectric/triboelectric hybrid generator(TCOHG)with an origami structure to enable effective energy harvesting.The proposed structure consists of a vertical contactseparation TENG on the surface of the triangulated cylinder,PENG on the inner hinge,and rotational TENG on the top substrate to harvest mechanical energy from each motion.Each generator could produce a separate electrical output with a single input.The TCO-HG could charge a 22μF commercial capacitor and power 60 LEDs when operated.
