感觉替换系统为其使用者提供通过与正常途径不同的感觉通路(眼、耳或皮肤)获得的环境信息或经过某种有效处理的信息。我们评述了用于展现视觉、听觉和作用于皮肤上的变形的触觉信息的方法。首先。我们讨论了感觉替换在目前和将来可能的应用,包括触觉、视觉替换(TVS)、触觉、听觉替换及触觉遥感或反馈(远触觉)。其次,我们回顾了有关的皮肤感觉生理,包括正常触觉的机理和用表面电极 Sensory replacement systems provide their users with environmental information or some sort of information that is effectively processed through sensory pathways (eyes, ears, or skin) that are different from the normal pathways. We reviewed the methods used to visualize, auditory, and distorting haptic information on the skin. First of all. We discuss the possible applications of sensory replacement in the present and future, including tactile, visual replacement (TVS), tactile, auditory replacement and tactile sensing or feedback (far-tactile). Second, we reviewed the relevant skin sensory physiology, including the normal tactile mechanism and the use of surface electrodes
