A 10-mV-Startup-Voltage Thermoelectric Energy Harvesting System Based on a Piezoelectric Cold Starter

Traditional power batteries have been unable to meet the requirements of wireless sensor network (WSN) applications which require battery lifetime and no battery replacement. So, harvesting ambient energy and converting it into electrical energy to power wireless sensors has become an alternative to the traditional power sources. Harvesting...

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...

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,...

Mechanical characterization and cleaning of CVD single-layer h-BN resonators

Hexagonal boron nitride is a 2D material whose single-layer allotrope has not been intensively studied despite being the substrate for graphene electronics. Its transparency and stronger interlayer adhesion with respect to graphene makes it difficult to work with, and few applications have been proposed. We have developed a transfer technique...
