A prosthetic device ( 12 ) and liner ( 14 ) form a prosthetic system ( 10 ) that can substantially mimic the cosmetic and functional qualities of a human hand. A harness ( 22 ) is adapted to fit about a remnant portion ( 16 ) of a hand ( 18 ). The harness has an opening ( 26 ) for accommodating the liner ( 14 ). A moveably mounted opposition member ( 24 ) is supported by the harness ( 22 ) and sensors ( 60, 62 ) positioned about the harness ( 22 ) detect a force exerted by an area ( 40 ) in proximity to the hypothenar eminence of remnant portion. Once a force is detected by either sensor ( 60, 62 ) a signal is communicated to a controller ( 70 ) which activates a motor ( 100 ) causing motion of the opposition member ( 24 ).
