Claim 8:
9. An upper-extremity prosthetic comprising:
a first member having a surface adapted to engage with an athletic ball;
a first spring coupled to the first member and arranged to deflect and to provide energy return in response to movement of the first member, wherein the first spring comprises a coil spring including a first portion made of a first material and a second portion made of a second material that is electrically conductive, wherein the second portion comprises a portion of an outer surface of the first spring and is at least partially encapsulated within the first material along a length of the coil spring, and wherein the second portion has an electrical conductivity that: (i) is greater than an electrical conductivity of the first portion and (ii) changes in response to deflection of the first spring;
a base member coupled to the first spring and pivotably coupled to the first member at a revolute joint, wherein the revolute joint comprises a pair of conical protrusions that movably reside within a pair of conical recesses;
a guide sleeve defining an internal space;
a shaft slidably extending within the internal space, wherein the first spring winds around the guide sleeve and the shaft, wherein the shaft and the internal space are each curved to match an arc defined by rotation of the revolute joint between the first member and the base member; and
a first cantilever spring extending from the first member and having a surface adapted to engage with an athletic ball while the athletic ball is also engaged with the surface of the first member.
