Abstract:
This paper designs a bionic artificial hand that has a tactile sensing, two degrees of freedom, driven by surface electro-myography (SEMG). The tactile sensor applying PVDF as a sensitive material, fitted the finger of artificial hand, has a good dynamic response. The tactile sense is spread to the user by an electric shock generator. Using improved power spectrum ratio and data fusion method based on statistical decision-making of Bayes, the movements of hand are recognized from SEMG. The experiment proves that it is a good way that the hand is controlled by SEMG combining with tactile sensor.
