假肢控制中感知反馈技术的研究进展

      Research Progress on Sensory Feedback Technology in Prostheses

      • 摘要: 假肢作为截肢患者实现健全肢体能力的重要辅具,简单的装饰性和单一前馈控制通路已经难以满足需求。为使假肢能够感知温度、压力、位置、形状等信息,多种感知反馈方式已被整合到假肢中。根据反馈终端在人体上的位置,将感知反馈系统分为侵入式反馈和非侵入式反馈。综述了两类感知反馈技术研究现状,并总结了其在假肢中应用存在的问题,展望了其发展趋势。

         

        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.
