Abstract: In recent years, the bidirectional bio-machine interface with the ability of neural control and sensory feedback has become the development trends of intelligent upper limb prosthesis. Most of the research focuses on the mechanism, sensor design and neural control of upper limb prosthesis, while less research on sensory feedback. The lack of reliable sensory feedback reduces the operational performance and limits the practical application of prosthetics. Firstly, the development status of bidirectional bio-machine interface of intelligent prosthesis is briefly summarized. Sensory feedback methods based on transcutaneous electrical nerve stimulation, vibration stimulation and pressure stimulation are introduced in detail. Sensory feedback strategies including sensory substitution, modality matched feedback and somatotopic matched feedback are also discussed. Based on the analysis, the naturalness of upper limb prosthetic sensory feedback and the multimodality of interactive information are prospected.
