In recent years,owing to the growing maturity of Inter-net of Things technology and mobile communication tech-nology,intelligent wearable devices have developed rapidly.They have been widely applied in aviation,medicine,mil-itary,entertainment and other fields.Through intelligent wearable devices,people can communicate efficiently,dy-namically perceive external environments,and monitor the body's vital signs.The devices can also timely feedback and process information[1,2].However,on the one hand,wear-able devices are restricted by the requirements of comfort,portability and miniaturization.On the other hand,tra-ditional batteries also have problems such as large quality,large volume,short battery life and limited power supply life.In addition,non-active power generation has low power density and poor continuity,which is not enough to sup-port equipments for a long time.Energy supply has been the bottleneck restricting further development of wearable devices.
