Design of mechanical structure of Th Vi PiEHs and electronic interface of hybrid energy harvesters

Abstract

The aim is to harvest energy from ambient vibration and ambient temperature in order to power sensors in an extreme environment such as nearby thermal engines in cars. Piezoelectric, pyroelectric and thermal expansion effects are the principle of energy conversion. The energy harvested from ambient temperature is considered in our work as additional to the energy harvested from ambient vibration, and not as the principal source.
