摘要：

Harvesting vibration energy from the environment using piezoelectric energy harvesters (PEHs) helps achieve battery-free embedded devices. Synchronous electric charge extraction (SECE) has load-independent power out-put. It is suitable for harvesting energy from multiple piezo-electric transducers. This paper presents a self-powered SECE interface circuit for piezoelectric energy harvesting. The proposed interface circuit implements a passive zero-crossing detection, harvests energy from multiple piezo-electric transducers with only one inductor, and outputs 79.3% more power than a standard full bridge rectifier in experiment.
