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 ER -
