Abstract
Springs can provide energy return and have a conductivity that changes in relation to an amount of strain or deformation of the spring. An upper-extremity prosthetic device includes a first coil spring coupled to a first member and a first cantilever spring extending from the first member to a surface adapted to engage with an object. The first coil spring is arranged to absorb energy and to provide energy return in response to movement of the first member. The first coil spring includes a first conductive surface and a second conductive surface separate from the first conductive surface by non-conductive surfaces. The first cantilever spring includes a conductive trace with a plurality of conductive segments arranged on the conductive trace.
