摘　　要：With the ever-growing demand for renewable energy sources,energy harvesting from natural resources has gained much attention.Energy sources such as heat and mechanical motion could be easily harvested based on pyroelectric,thermoelectric,and piezoelectric effects.The energy harvested from otherwise wasted energy in the environment can be utilized in self-powered micro and nano devices,and wearable electronics,which required onlyµW–mW power.This article reviews pyroelectric energy harvesting with an emphasis on recent developments in pyroelectric energy harvesting and devices at micro/nanoscale.Recent developments are presented and future challenges and opportunities for more efficient materials and devices with higher energy conversion efficiency are also discussed.
