An Implanted Telemetry System for Transcutaneous Biosignal Transmission

This paper presents the initial project developments of a radio-based system to transmit EMG signals from within the body to the outside without using transcutaneous cables. Due to current electronic system getting smaller and the development of new biocompatible materials, biomedical implants are becoming much more common. No current implantable system, either commercially available or reported in the research literature, deliver the combination of channel count, bandwidth and long operation time without battery change required for our application. The proposed research will overcome these limitations. Signals are digitised and transmitted through the skin wirelessly over high bandwidth. Power is supplied by radio frequency induction, from an external coil placed over the back of animal.
