摘要
针对弧形结构能量采集器进行了研究和构建,该采集器实现了压电、摩擦纳米发电机之间的整合,可用于实现振动机械能到电能之间的转换,从而实现对小型传感系统的供电,弥补了传统供能方式的弊端。在研究过程中,测试了该采集器的输出性能,划分为压电单元、摩擦单元两部分,二者整流之后的输出短路电流依次是0.9μA和1.25μA,开路电压依次是10 V和60 V。该采集器除了可以实现对电容充电的功能之外,同样可以驱动50个并联的LED。相对于传统的能量采集器,其可以对不同方向的机械能进行采集,因此适用性更强,适合于应用到小型器件供能中。
Energy collector with arc⁃shaped structure is researched and constructed.The collector realizes the integration between piezoelectric and friction nano⁃generators,which can be used to realize the conversion from vibration mechanical energy to electrical energy,thus realizing the power supply for small sensing systems,and making up for the disadvantages of traditional energy supply mode.During the research,the output performance of the collector is tested,which is divided into two parts,piezoelectric unit and friction unit.The output short⁃circuit current after rectification is 0.9μA、1.25μA.The open⁃circuit voltage is 10 V and 60 V.In addition to the capacitor charging function,the collector can also drive parallel 50 LED.Compared with the traditional energy collector,it can collect the mechanical energy in different directions,so it has stronger applicability and is suitable for application in energy supply of small devices.
