Abstract

A novel miniaturized transmitting (TX) and receiving (RX) wireless power transfer (WPT) resonators operating at 6.78 MHz integrated with antenna for medical implant communication service (MICS) band (402 MHz-405 MHz) are devised and presented. Integration of resonators into wireless power system and optimization of matching circuit are discussed. The prototype model is fabricated and tested in vitro, using human body phantom mimicking electrical properties of the human body tissues. The power transfer efficiency (PTE) of 30% at 20 mm distance and implanted antenna gain of -23 dBi are confirmed via simulations and measurements.
