Influence of a Medium on Capacitive Power Transfer Capability
2022 Wireless Power Week (WPW), 2022 Despite the advantages of capacitive power transfer (CPT), inductive power transfer (IPT) is still preferred. The reason: IPT systems have a gap power density in air that is 400 times greater. Conclusively, IPT can transmit more power than CPT over greater distances in air, but what about other media?
