A conductive human interface has a fabric layer with an interior surface and an exterior surface. A soft coating overlies the interior surface of the fabric layer. An electrode or sensor is included to connect with a residual limb. A conductive path connects the electrode or sensor with an electrical connector which, in turn connects with a prosthetic or other assistive device. The conductive path includes a conductor having a section overlying the fabric layer. The overlying section of the conductor can be cord of conductive thread. A nonconductive support thread can extend through the fabric layer from the exterior surface to the interior surface, and further around the conductor to secure the overlying section of the conductor to the fabric layer.

Conductive human interfaces

A conductive human interface includes an insulating body of elastomeric material and a compliant electrode embedded in the insulating body. The electrode is formed from an electrically conductive gel including a polymeric material and conductive particles dispersed in the polymeric material. The conductive particles can be included in the gel in an amount that is not more than about 10% by weight.

A prosthetic foot structure includes a plate assembly having a toe portion and a heel portion. The plate assembly includes a first plate adjoining a second plate along a seam at which the first plate is bonded to the second plate. The seam has an end between the first and second plates, and the first plate is spaced from the second plate across a gap that reaches away from the end of the seam. An attachment structure attaches the first plate to second plate. The attachment structure has a composite composition including a resin material containing reinforcing fibers. The reinforcing fibers reach through the first plate, across the gap, and through the second plate.

A solid state thermal control device contains a substrate and a plurality of solid state thermal elements on the substrate. The thermal elements are adapted to provide thermal control to a device under test (DUT). Each solid state thermal element contains at least one solid state heater and an active control circuit adapted to control a thermal output of the heater. Optionally, the each thermal element may also include a solid state temperature sensor.
