Single terminal and double terminal coil shape analysis using capacitive power transmission for biomedical implant

This paper proposed a transmitter antenna using single terminal coil shape design and receiver antenna using double terminal coil shape design (Cs-Cd) to enhance the electric and magnetic coupling for Capacitive Power Transfer system to achieve higher energy transmission. This method used only single transmitter antenna instead of two transmitter antennas for power transmission. This design configuration was compared with other four configurations using either capacitive power transfer or inductive power transfer. As a result, Cs-Cd configuration achieved higher receiving power at longer implantation distance and lower temperature heating compared to conventional inductive power configuration. This method showed a better approach to power wirelessly miniaturized implant medical device.
