摘要:
Various aspects of this disclosure relate to a prosthetic cover comprising an array of sensors, which transmit signals to an array of electrodes in a liner that fits over a residual limb of an amputee. Different interactions with the prosthetic cover cause different activation of the electrodes to transmit electrical current through different areas of the residual limb and modulate neurons differently within the residual limb. Various aspects of this disclosure also relate to a prosthetic liner with a substrate that includes electrodes for transcutaneous electrical nerve stimulation and/or electronic muscle stimulation for a residual limb.

摘要:
A method for controlling the standing-phase damping of an artificial knee joint comprising an upper part and a lower part which are secured together in a pivotal manner about a pivot axis, a resistance unit which is arranged between the upper part and the lower part and has an adjustment device via which the damping resistance can be modified, and a control unit which is coupled to the adjustment device and which is connected to at least one sensor. The adjustment is carried out on the basis of sensor data, and the knee angle is detected by the at least one sensor during the standing-phase inflexion up to the terminal standing phase. The flexion damping is increased to a level above an initial flexion damping in order to prevent a further inflexion upon reaching a specified maximum knee angle.

An adjustment-free multi-stage prosthesis air cylinder is used in a prosthesis joint and has an air cylinder body, a piston assembly slidably mounted on the air cylinder body, a first check valve mounted in the piston, and a multi-stage air pressure valve mounted inside a lower air way of the air cylinder body. The multi-stage air pressure valve automatically cushions movements of the piston assembly without being adjusted whenever a user of the prosthesis joint walks slowly or quickly, so to allow the user to feel comfortable.

High resolution active matrix nanowire circuits enable a flexible platform for artificial electronic skin having pressure sensing capability. Comb-like interdigitated nanostructures extending vertically from a pair of opposing, flexible assemblies facilitate pressure sensing via changes in resistance caused by varying the extent of contact among the interdigitated nanostructures. Electrically isolated arrays of vertically extending, electrically conductive nanowires or nanofins are formed from a doped, electrically conductive layer, each of the arrays being electrically connected to a transistor in an array of transistors. The nanowires or nanofins are interdigitated with further electrically conductive nanowires or nanofins mounted to a flexible handle.
摘要:
A vacuum pump system for a prosthesis device includes an enhanced suspension mechanism and cooperates with a pressure source, an adaptor assembly, circuitry, and a power source. A virtually air-tight seal between a residual limb and a socket of the prosthesis allows a vacuum fit to be generated by the pump system. The pump system may be controlled with various circuits and processors receiving instructions from a software program. The pump system may be located within a pylon, but yet remain vibrationally and acoustically de-coupled from the pylon.
