Implementing a Bluetooth EMG System Comprising a Subcutaneous Sensor and the Associated Transceiver

We implemented a Bluetooth Low Energy system concerning the acquisition, encryption, wireless transmission, and reconstruction of the electromyographic signal for prosthetic control. The system is expandable with other devices supporting Bluetooth and is a valuable alternative to the current proprietary implantable EMG systems, which use restricted protocols and ignore data security. The adopted system-in-package has ultra-small dimensions and encloses an integrated antenna, thus additional space in the implant or the prosthesis is not required. It includes peripherals embodying advanced solutions for buffering the signal and prosthetic control, including wired digital protocols, Bluetooth, and analog signal reconstruction features. All this embracing the development for the next generation of myoelectric prosthetic control.
