用于压电能量收集的高增益、负载容忍型串并联同步开关技术

In the framework of autonomous wireless devices (e.g., sensors) powered by energy available from their surrounding environment, this article exposes a technique combining the so-called series and parallel Synchronized Switch Harvesting on Inductor (SSHI) approaches for piezoelectric energy harvesting. More specifically, the proposed circuit consists in switching the piezoelectric element on two in...
