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 PV-assisted 10-mV Startup Boost Converter for Thermoelectric Energy Harvesting

This paper presents a boost converter for thermo-electric energy harvesting with photovoltaic (PV)-assisted startup. The converter employs a new two-phase startup architecture and the PV cell is used in the first phase to provide an initial high voltage for startup. This high voltage drives the boost converter to charge a startup capacitor,...

A 10-mV-Startup-Voltage Thermoelectric Energy Harvesting System With a Piezoelectric Starter

An ultra-low-startup-voltage thermoelectric energy harvesting system assisted by a piezoelectric generator (PEG) is presented in this paper. When the energy harvesting system is implemented in a place where there is mechanical vibration, the associated PEG can generate a stable clock signal and drive the boost converter to start from the cold...
