Abstract

Sensors mounted in tires require a continuous power supply, currently from batteries. Piezoelectric energy harvesting is a promising technology to harvest energy from tire movement and deformation. This study presents a new simulation method to model simultaneous the combination of tire deformation and piezoelectric harvester with dynamic bending zone. The approach combines numerical simulations in COMSOL Multiphysics with real-life measurements of electrical output of a piezoelectric energy harvester mounted on a tire. In the simulation, angular and initial velocities were used for rolling motion, angled polarization was introduced in the model for the piezoelectric material to generate correct voltage from tire deformation. Experimental measurements conducted at Nokian Tyres and RISE show good agreement with dynamic simulation. The study also shows the importance of optimizing the harvester's geometry for maximum electrical output which can power some tire sensors.
