Abstract:As an important research content in the field of rehabilitation,intelligent myoelectric prosthetic hand research has always been a hot research spot through the world.With the advancement of robotics,the prosthetic hand is moving toward humanoid type,dexterity,intuitive control,and intelligent perception.The intelligent myoelectric prosthetic hand should have similar function with human hand.It not only assists the daily life of the disabled by rebuilding motor function,but also recreate the proprioception by restoring the perceptual feedback function.This paper reviews years of domestic and foreign research results on myoelectric prosthetic hand and analyzes the mechanical design of the prosthetic hand from the perspectives of weight,dexterity,grasping performance,and design principle.In the area of user motion intention decoding,this study systematically summarizes the state-of-the-art in gesture recognition based on surface electromyography signals,and introduces various of research ideas based on residual limb biological signal recognition.In addition,a variety of prosthetic hand tactile perception technologies based on different principles are analyzed,and adaptive control and user awareness feedback using the finger tip force tactile sensor are introduced.Finally,the problems and challenges faced in the research and development of prosthetic hands are summarized,and the direction of future research in myoelectric prosthetic hand is proposed.
