The characterization of class E Pi1B capacitive power transfer for biomedical implantable device application

The use of Wireless Power Transfer (WPT) technology for recharging or providing a continuous supply of electricity to Biomedical Implantable Devices (BID) has become very useful recently. To date, Inductive Power Transfer (IPT) remains the most popular technique used to transmit power and data betwe...
