一种用于无电池无线传感器应用的超低静态电流最大功率点跟踪

This paper presents a chip-scale ultralow quiescent current power management system that interfaces with electromechanical energy harvester for enabling self-powering, batteryless wireless sensors. A piezoelectric transducer scavenges and transforms mechanical vibration energy into electricity in ac form, which is then converted into dc power by a full bridge rectifier and collected into a small f...
