Review on tactile sensory feedback of prosthetic hands for the upper-limb amputees by sensory afferent stimulation

摘要: Loss of sensory function for upper-limb amputees inevitably devastates their life qualities, and lack reliable feedback is the biggest defect to sophisticated prosthetic hands, greatly hindering usefulness perceptual embodiment. Thus, it extremely necessary accomplish an intelligent hand with effective tactile amputee. This paper presents overview three kinds existing approaches, including cutaneous mechanical stimulation (CMS), transcutaneous electrical nerve (TENS) direct peripheral (DPNES). The emphasis concentrates on major scientific achievements, advantages disadvantages. TENS skin areas evoked finger sensation (EFS) at amputees’ residual limbs might be one most promising approaches realize natural feedback.
