Implantable EMG measuring system

The development of a multi-channel, implantable EMG measuring system is presented. The system integrates an application specific integrated circuit for EMG acquisition. Inductive coupling is used to supply the ASIC, an ARM Cortex-M4 microcontroller and a wireless data transmission in conformity with the medical implant communication service. Additional monitoring functions like electrode resistance, temperature and humidity measurement are implemented to monitor the reliability of the system. The implant is projected to control hand prostheses by EMG monitoring.
