Design of Wireless Power and Data Transmission Circuits for Implantable Biomicrosystem

Ghazi Ben Hmida, Hamadi Ghariani and Mounir Samet
This study describes the design of an inductive powering system that combines power transfer with data transmission for implantable biomicrosystem. The implant receives power from an external transmitter through an inductive link between an external power transmission coil and the implanted receiving coil. We designed a transmitter with class E power amplifier to provide maximum power with high-efficiency. It is possible to obtain about 136 mW of power in the secondary system with an efficiency of about 50%. A bit rate of 1 Mbps is achieved for sending command data to the implant. We propose a communication system for the medical implants which uses inductive link. This system is consisted of a class E power amplifier, an ASK modulator, an inductive link and an ASK demodulator.

Hello,
I want to take permission to use the Figure. 1, circuit image in my review paper.
There is no permission option in link.
Can I use this image
