Research Progress on Sensory Feedback Technology in Prostheses / 中国医疗器械杂志

ABSTRACT

As an important auxiliary tool for amputees to gain abled limb functions, prosthetic limbs with decoration or feedforward control channel could not meet the needs. In order to enable the prosthesis to deliver the information, includes temperature, pressure, position, shape and so on, a variety of sensory feedback methods have been integrated into the prosthesis. According to the position of the feedback terminal on the human body, the perceptual feedback systems include invasive and noninvasive sensory feedback. This review presents the research progress of these perceptual feedback techniques, and summarizes the problems in the application in artificial limbs. Finally, the development trend of sensory feedback technology in prostheses is prospected.
