Patent Images
1. An instrumented prosthetic foot for use with an actuated leg prosthesis controlled by a controller, the instrumented prosthetic foot comprising:
- an elongated body comprising a foot plate and a heel plate being cantilevered from the foot plate, the foot plate comprising a toe region thereof;
a connector to connect the instrumented prosthetic foot to the leg prosthesis, the connector being mounted on the elongated body; and
a pair of first and second sensors mounted on the elongated body, the first sensor being positioned at the underside of the heel plate and the second sensor being positioned at the underside of the foot plate at the toe region;
wherein the pair of first and second sensors is configured to detect changes in weight distribution along the prosthetic foot.
