US Patent 9192487 Joint control systems and methods utilizing muscle activation sensing

A system and method for controlling a prosthetic limb are provided. A sensor component receives input from a wearer's muscle and provides a signal to a control component. The sensor component may be a force sensing resistor placed inside a socket of a prosthetic limb between a residual limb and the hard side of the socket. The control component processes the signal and provides instructions to an actuation component. In this manner, an actuation component may move a joint, or may change the velocity of a joint, or may change other characteristics of the prosthetic limb.
