提出了一种系统，将环境机械振动转换为电能，用于为自主低功率电子系统供电，通过使用可变电容器来转换能量，利用微机电系统（MEMS）技术，为该系统设计了这样的设备。低功耗控制器 IC 采用 0.6μm CMOS 工艺制造，并经过损耗测试和测量。根据测试，该系统预计可产生 8 muW 的可用功率。除了所制造的可编程控制器之外，还描述了一种基于超低功耗延迟锁定环（DLL）的系统，该系统能够自主实现振动频率的稳态锁定。
A system is proposed to convert ambient mechanical vibration into electrical energy for use in powering autonomous low power electronic systems, The energy is transduced through the use of a variable capacitor, Using microelectromechanical systems (MEMS) technology, such a device has been designed for the system. A low-power controller IC has been fabricated in a 0.6-mum CMOS process and has been tested and measured for losses. Based on the tests, the system is expected to produce 8 muW Of usable power. In addition to the fabricated programmable controller, an ultra low-power delay locked loop (DLL)-based system capable of autonomously achieving a steady-state lock to the vibration frequency is described.
