可穿戴设备高效自供电结构设计研究
摘要
Abstract
Based on Faraday's law of electromagnetic induction and the principle of piezoelectric effect,a self-powered wearable device is designed in this paper,which includes a main body of the equipment and a power supply device installed in the main body of the equipment,which includes a combined power generation module,a circuit board and a battery.The combined power generation module consists of coils,strong magnets and several groups of piezoelectric ceramic pieces.The combined power generation module generates electricity through the electromotive force generated by the strong magnet passing back and forth through the coil and the strong magnet striking the piezoelectric ceramic piece.The coil and the piezoelectric ceramic piece are electrically connected with the circuit board respectively.The circuit board,the battery and the main body of the equipment are electrically connected in turn.The self-powered wearable device can convert kinetic energy into electric energy through a combined power generation module,which is not only fast to generate electricity but also easy to wear.Importantly,this wearable device can save energy through the self-powered supply system.关键词
