摘要
基于法拉第电磁感应定律和压电效应原理,该文设计一款自供电可穿戴设备。该设备包括设备主体和安装于设备主体内的供电装置,供电装置包括组合发电模块、电路板、电池,组合发电模块包含线圈、强磁体及若干组压电陶瓷片,组合发电模块通过强磁体来回穿过线圈产生电动势和强磁体撞击压电陶瓷片产生电动势实现发电,线圈和压电陶瓷片均分别与电路板电连接,电路板、电池及设备主体依次电连接。该自供电可穿戴设备通过组合发电模块能够将动能转变为电能,不仅发电快而且穿戴便捷,重要的是,这种可穿戴设备可以通过自供电系统节约能源。
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.
