Abstract: Objective To realize the tactile and slip sensory functions for electromyogram controlled prosthetic hand. Methods The piezoelectric membrane polyvinylidence floride (PVDF) was used to construct a transducer for the tactile and slip sensory feedback. The feature and piezoelectric response of PVDF and its mechanism of signal production were studied. The feedback control system was designed and a prototype for testing the tactile and slip sensor function was constructed and tested. Results and Conclusion The signal response of PVDF sensor is obviously, and the PVDF sensor can be used in practice.

Key words: bionic prosthetic hand, tactile and slip feedback, piezoelectric membrane sensor
