In order to make prosthetic hands acting like human hands as much as possible and improve the biomimetics and intelligence, it is necessary to add multi-sensor perception system on electric prosthetic hand system. In this paper, the theory of sEMG and its signal analysis technology are introduced. SEMG sensing techniques for hand prostheses are surveyed. These sensing techniques include tactile and slip sensing, proximity sensing, cold and hot sensing, and multi-sensing fusion. Meanwhile these prosthetic hands sensors and sEMG sensing techniques are compared. Some further researches and developing trend of sEMG sensing techniques for hand prostheses are indicated.
