it looks and moves like a high-end electronci hand. 

A more durable production version, which will use tougher plastics and
sleeker parts, could be on the way as early as this winter. Edison Nation, a
company that helps inventors develop their ideas, recently selected Stark's
hand for commercial development and is now in talks to license it to a major
prosthetics manufacturer.
