Sustainable power supply to flexible electronics is currently of high interest due to the transition to
autonomous and self-driving vehicles. Piezoelectric Energy Harvesters (PEH) can be used as sustainable
energy sources by harvesting the electrical power through the material deformation occurring in tire. In
this work, an analytical setup was developed to experimentally validate the energy harvesters for their
use in tires. It was designed to measure the harvested electrical energy under simulated driving
conditions. The setup includes a Dynamic Mechanical Analysis (DMA) as foundation to simulate the
vibrations and dynamic responses occurring in a rolling tire. The dynamic properties and the output
voltage from the harvesters were monitored under these sinusoidal conditions. For this, a PEH for tire
applications was prepared in a sandwich configuration. It consists of a piezoelectric material, i.e.
PolyVinyliDene diFluoride (PVDF) film, inserted in between two layers of electrodes, i.e. elastomers
filled with conductive carbon black fillers. Electrical conductivity of elastomeric compounds was
measured under dynamic conditions varying dynamic strain, frequencies, temperatures. It resulted that
dynamic strain and temperature were the most significant factors influencing the electrical conductivity
of elastomers. Output power from piezoelectric energy harvester was also measured varying frequencies
and temperatures. Both properties increase considerably the piezoelectric power. This development
gives a promising method for analyzing the electro-mechanical properties of conductive and
piezoelectric materials and optimizing their performance according to simulated tire-rolling conditions.
