Over the past decade, energy harvesting from the surrounding resources has been a hot topic for numerous researches. The automotive industry is one field that pays attention to this clean energy which plays a primary role in the vehicle’s safety. Moreover, a cost-efficient monitoring structure to better track tires conditions is required to fill the tires safety requirements. The main objective of this paper is to present a state of the art about the techniques of vibrational energy harvesting from car’s tires for the embedded self-power sensors and tires condition monitoring systems (TCMS).

This paper aims to evaluate the voltage and the electrical power harvested from the car suspension system under bump excitation using a piezoelectric stack. For this purpose, a quarter car system equipped with a piezoelectric stack installed parallel to the suspension's damper is modelled and investigated in temporal domain using MATLAB/Simulink. The studied system is excited, considering different bump amplitudes to evaluate the harvested voltage and power at different speeds. The effect of the suspension's damping coefficient on the harvested voltage and power is also studied and quantified.
