The invention relates to a sensor support (10) for arranging on a prosthesis, comprising a main part (20) for receiving sensors, said main part (20) having a sensor section (25) comprising sensors. The main part (20) has a holding section (30) for holding the main part (20) on a prosthesis part and a knitted fabric tube (21). The holding section (30) has a first knitted structure (32) which allows a secure hold of the main part (20) on the prosthesis part, and the sensor section (25) has a different knitted structure (27) which allows a secure positioning of the sensors relative to the prosthesis part.

A prosthetic foot comprises an attachment member and two or more flexible members. The attachment member can include a connector configured to connect the attachment member to a user or another prosthetic device. The two or more flexible members can be rotatably attached to the attachment member by rotatable joints such that the flexible members can both rotate and flex relative to the attachment member when the prosthetic foot contacts the ground.

A prosthetic device includes a frame defining an output axis, a cantilever beam spring attached to the frame, a moment arm attached to the spring, and a rigid output arm coupled to the frame and rotatable about the output axis. A connector assembly is configured to apply a moment to the cantilever beam spring via the moment arm while applying a torque about the output axis via the output arm. An ankle-foot device includes foot and ankle members connected for two-degree of freedom movement relative to one another, allowing for rotation about an ankle axis and rotation about a subtalar axis. Two linear actuators, each coupled to corresponding series elastic element, link the foot and ankle members. Driving the actuators in the same direction causes rotation about the ankle axis and driving the actuators in opposing directions causes rotation about the subtalar axis. A processor receives sensory information from a sensor and drives the actuators to control an equilibrium position of the series elastic elements. A rotary actuator for a prosthetic device includes a housing frame, a motor mounted within the housing frame, and a cycloidal drive coupled to the motor within the housing frame. A torsion shaft can extend through the actuator to an output and provide a series elastic element.

A dynamic support apparatus having a frame, a dynamic interface, a temperature control mechanism, and a control system. The dynamic interface is capable of changing its geometry and is disposed on the top surface of the frame. The control system is operably connected to the dynamic interface and controls the changing geometry of the dynamic interface. There is also a temperature control mechanism disposed on the top surface of the frame for maintaining a comfortable temperature and moisture environment between the apparatus and the user's body.

The present invention discloses a system and method for motion recognition and control of a prosthetic device. The system of the present invention uses a movement detector for detecting dimensional motion of a non-disabled physical appendage and generating motion information based on this detecting. The system further includes a microcontroller adapted to be connected to the movement detector for receiving and processing the motion information transmitted from the one or more movement detectors. The system controls a prosthetic device which has actuators that are configured to actuate motion of the prosthetic device based on the processing of the motion information.

The devices can include a proximal portion configured to receive an appendage of a user; a distal portion configured detect sensory information; an articulation positioned between the proximal and distal portion to provide for motion of the distal portion via manipulation of the proximal portion; wherein the distal portion comprising a sensing element and the proximal portion comprises a feedback element, the feedback element being connected to the sensing element providing for physical extension of sensory capabilities of the appendage.

Prosthetic and/or orthotic devices (PODS), control systems for PODS and methods for controlling PODS are provided. As part of the control system, an inference layer collects data regarding a vertical and horizontal displacement of the POD, as well as an angle of the POD with respect to gravity during a gait cycle of a user of the POD. A processor analyzes the data collected to determine a locomotion activity of the user and selects one or more control parameters based on the locomotion activity. The inference layer may be situated between a reactive layer control module and a learning layer control module of the control system architecture.
