CSEM : The first dexterous and sentient hand prosthesis has been successfully implanted
In a pioneering surgery, titanium implants were placed in the two forearm bones (radius and ulnar), from which electrodes to nerves and muscles were extended to extract signals to control a robotic hand and to provide tactile sensations. This makes it the first clinically viable, dexterous and sentient prosthetic hand usable in real life. The breakthrough is part of the European project DeTOP.
As part of the DeTOP consortium, CSEM developed a low-power integrated circuit which enables two key functions: control of the prosthetic hand and collection of sensory feedback. The main challenge was to develop an implantable circuit, therefore highly miniaturized and low energy, while still providing the demanding processing performances required by the prosthetic application. Capitalizing on CSEM's pioneering work in miniaturized low-power consumption electronics, the circuit is based on its icyflex2 processor and icyTRX radio transceiver. In addition, an optimized integrated analog front end was developed for the sensor interface. The circuit supports a real-time communication protocol, also designed by CSEM, which frees the control unit of cabling.
The DeTOP project pushes boundaries by clinically implementing robotic, sensing and long-term interfacing technologies and we are pleased to have been able to contribute core technology for this next-generation digital health device which is destined to transform the lives of amputees around the world,
says Stéphane Emery, Head of System-on-Chip at CSEM.
