The developed Smart Illuminative Charging is a novel wireless charging system that uses LEDs powered by piezoelectric materials as the energy transmitter source and thin film solar panels placed at the bottom of the EVs as the receiver, which is then poised to deliver the harvested energy to the vehicle's battery. The piezoelectric materials were tested for their mechanical-to-electrical energy conversion capabilities and the relatively large-area EH2N samples (2 cm × 2 cm) produced high output voltages of up to 52 mV upon mechanical pressure. Furthermore, a lab-scale prototype device was developed to testify the proposed mechanism of illuminative charging (i.e., "light" coupled pavement and vehicle as a wireless energy transfer medium).Attribution 4.0 United Stateshttps://creativecommons.org/licenses/by/4.0/wireless chargingelectric vehiclespiezoelectric effectLEDssolar panelsArticle2023-01-20
