There are no commercially available myoelectric prosthetic systems that provide sensory feedback. This means that the user does not know if they are contacting an object or how hard they are squeezing, which can make accurate control of the device challenging.
A tactile feedback system is being developed that will provide touch information directly to the user. A sensor on the prosthesis measures applied forces, and the signal is translated to the user with a tactor, which pushes onto their skin to give them an indication of grasping force. We are now working on integrating sensory feedback devices into prosthetic sockets for clinical trials.
