A Thermoelectric Energy Harvesting System Assisted by A Piezoelectric Transducer Achieving 10-mV Cold-Startup and 82.7% Peak Efficiency

This article presents a 10mV-startup-voltage thermoelectric energy harvesting system, assisted by a piezoelectric generator (PEG) as a cold starter. It exploits the fact that when a thermoelectric energy harvesting system is implemented in a place where kinetic energy is also present, the PEG starter can provide a clock signal to start the...

A Bias-Flip Rectifier With Duty-Cycle-Based MPPT for Piezoelectric Energy Harvesting

Bias-flip rectifiers are commonly employed for piezoelectric energy harvesting (PEH). This article proposes a synchronized switch harvesting on an inductor (SSHI) rectifier with a duty-cycle-based (DCB) maximum power point tracking (MPPT) algorithm. The proposed DCB MPPT algorithm is based on the mathematically derived relation between the...
