Prosthesis and orthosis slip detection sensor and method of use

A prosthetic socket system comprising;

• a flexible prosthetic socket adapted to fit at least one slip detection sensor device;
• the at least one slip detection sensor device is configured to measure movement inside the prosthetic socket relative to a residual limb including socket rotation and multidirectional socket slip and embedded laterally within at least one socket wall of the prosthetic socket wherein the at least one slip detection sensor device is comprised of
• an optoelectronic sensor;
• a processing unit electrically connected to the optoelectric sensor;
• a power source electrically connected to the processing unit;
• a light source connected to the power source;
• and
• a housing containing the processing unit and the power source;
• a suspension system for attaching the prosthetic socket to a residual limb;
• adjustment means connected to the suspension system to change a fit of the socket with the residual limb;
• a motion capture system configured to detect soft tissue deformation;
• and
• software configured to measure feedback relating to the multidirectional socket slip, the socket rotation, and the soft tissue deformation and control the adjustment means to change the fit of the socket in response to the measured feedback;
• wherein the feedback comprises a comparison between the multidirectional socket slip, the socket rotation, and the soft tissue deformation to a threshold, and if the multidirectional socket slip, the socket rotation, and the soft tissue deformation exceed the threshold, the software is configured to send a signal to the adjustment means to change the fit of the socket.
