Project Title:
Wireless Non-Invasive Advanced Control of Microprocessor Prostheses and Orthoses

Summary:
There are several current and imminent prosthetic fitting scenarios that would greatly benefit from the ability to wirelessly collect and transmit physiological information from the user using a sensor. These strong candidates include both upper and lower-limb orthotic and prosthetic fittings that use osseointegration, have cable management issues, or benefit from various forms of physiological information from locations remote to the prosthetic socket.

Some wireless IMUs, EMG sensors, etc. currently exist, but they were developed for more general biomechanics research applications. They’re too large, too heavy, and/or are not sufficiently robust for field use in a prosthesis. In addition, these sensors have a variety of communication protocols that do not allow them to be easily integrated into today’s prosthetic systems. Our target solution is to develop sensors that can collect several modalities of physiological information from the user and transmit it wirelessly to the prosthesis.
