The bionic control of prosthetic hand is a challenging problem in prosthesis research, and researchers have explored the potential of using many physiological signals to provide simple, convenient and dexterous control with multiple degree of freedom. In this study, we suggest a new real-time control method for powered prosthetic hand based on our previous research results. This study designs an ultrasound-based prosthetic hand control system including A-mode ultrasound transmission and collection, prosthetic hand control, information processing and feedback, and etc. The control performance of the system was evaluated with normal subjects and the feasibility of ultrasound control of prosthetic hand was investigated. Experiment results show that ultrasound signal could control the continuous change of prosthetic hand's opening and closure position, which provides a simple method for grasp control. The results suggest that ultrasound signal, through further improvement, has great potential to be an alternative method for prosthesis control.
