Research on brain control prosthetic hand

By the development of biosensor, signal processing techniques and critical technical breakthrough, the concept of brain-computer interface has been extended and emphasized that the interface between brain and electromechanical equipment is involved rather than just computer. This development leads to the formation of new technical theoretical system - brain control technology. In this paper, the development of brain-computer interface is discussed, so that the new concept of brain-control is proposed. And then, the brain signals detection, intelligent prosthetic control, and the man-machine cooperation prosthetic model were firstly studied according to the humanoid operated mechanism. Further more, a neural prosthesis hand system driven by brain computer interface (BCI) was firstly constructed, which integrating the EEG signal detector system, EEG signal analyzing and recognition system and prosthesis hand control system. Finally, a wearable intelligent mind controlled prosthetic hand (IMCP Hand) was also designed with integration of multi-point tactile and slippery sensors in the prosthetic space and three-dimensional acceleration sensor information fusion, so that the neuro-prosthetic hand would have some chance to be applied in the disability people with upper limb.
