    Figure 1: Southampton hands. Across each palm can be seen a dc motor with a worm and wheel to rotate the thumb. Five other motors flex and extend the fingers and thumb. The fingertips have touch (force), slip/texture, and temperature sensors.

    Power management of an artificial hand
    Dr Paul H Chappell, Faculty of Physical and Applied Sciences, University of Southampton

    For an upper extremity amputee, mass is a main factor when choosing an artificial hand. A hand should be lightweight so that high pressure points do not develop inside the plastic socket that attaches
