The application of telemetric systems for monitoring and control of physiological functions poses many challenges in designing modules that can be inserted into the body with minimal intrusion, amplifying and controlling the minuscule signal generated by the body and then transmitting the signal to an external data reading system. This type of device can be used for monitoring and controlling nerve signals in patients with spinal cord injuries and drop foot and for acute reading in noisy electrical environments (such as operating theatres).

GE Aviation has been involved in the design and development in the development of medical telemetry systems in collaboration with University College London (UCL), particularly for the amplification of signals from the nerves, elimination of interference from internal and external sources and providing power for the device through integration of miniature radio frequency induction coils.
