Instrumented prosthetic foot

摘要

The present invention discloses an instrumented prosthetic foot for use with an actuated leg prosthesis controlled by a controller, the instrumented prosthetic foot comprising a connector to connect the instrumented prosthetic foot to the leg prosthesis, an ankle structure connected to the connector, a ground engaging member connected to the ankle, at least one sensor for detecting changes in weight distribution along the foot, and an interface for transmitting signals from the sensor to the controller.

主权项

1. A prosthetic foot comprising:
an elongated foot plate; a connector to operably connect the elongated foot plate to a user, the connector being connected in a manner that provides for multidirectional movement of the connector relative to the elongated foot plate; at least one solid sensor positioned between the connector and the elongated foot plate and positioned directly beneath the connector, the at least one solid sensor comprising a deformable material to provide for said multidirectional movement and configured to measure load on the prosthetic foot based on deformation of the deformable material; and a controller in communication with the at least one sensor and configured to communicate control signals to a device separate from the prosthetic foot based on data from the at least one sensor.
