<br/><br/> Energy harvesting from vibration are always based on reaching the resonant frequency by try to vibrate the harvester at its resonant frequency to maximize gained energy. Some systems have operation conditions that forces the designer to find a mechanism that maximizes harvested energy at off-resonant frequencies. The focus of the current work is to investigate the viability of a system that can supply a sensor mounted inside a car tire with sufficient power using energy harvesting principles of off-resonant frequency, as an example for the targeted sensors is a car tire air pressure sensor
