提出了一种对经皮电流刺激的皮肤触觉的触觉显示。由于自顶向下的设计方法表达了各种感觉（例如，由语言反馈表达的压力感觉、振动感觉、触觉感觉）已经用于许多过去的皮肤触觉显示器中，并且由于这些感觉是组合各种感觉受体的活动的结果，因此这样设计的显示器受到限制，因为它们仅显示某些有限的感觉。相比之下，作者的设备是基于刺激不同种类的感觉神经。人们认为，如果可以进行刺激，以适应不同种类的感觉神经，所有的感觉可以通过组合它们产生。这些刺激被称为“触觉原色”，因为它们与视觉相似。来自皮肤表面的电刺激被用作刺激手段。虽然电刺激本身的历史是古老的，但许多关于电刺激的研究最终产生了特别的简单感觉，而没有试图构建上述原色。本文提出了两种选择性刺激受体的方法。一种是通过使用阵列形式的电极改变每个电极的重量来改变刺激深度的方法。另一种是通过使用阳极电流在神经轴突的方向上选择性地刺激的方法，与过去方法的经皮电刺激中使用的阴极电流相反。(C)2002 Wiley Periodicals，Inc.
A tactile display of skin touch sensations to transcutaneous electric current stimulation is proposed. Since topdown design methods expressing various sensations (e.g., pressure sensation, vibration sensation, tactile sensation) expressed by language feedback have been used in many of the past skin touch sensation displays and since these sensations are the results of combining the activities of various kinds of sensory receptors, the displays thus designed have been limited in that they displayed only certain limited sensations. In contrast, the authors' device is based on stimulating sensory nerves differently by kind. It is considered that if stimulations can be performed to suit different kinds of sensory nerves, all sensations can be generated by combining them. These stimulations are called "tactile primary colors" from their similarity to the visual sense. Electrical stimulation from the skin surface is used as the stimulating means. Although the history of electrical stimulation itself is old, many studies regarding electrical stimulation have ended up generating ad hoc simple sensations without attempting to construct the above primary colors. In this paper, two methods for selectively stimulating the receptors are proposed. One is a method of changing the depth of stimulation by changing the weight of each electrode, using electrodes in an array form. The other is a method of selectively stimulating in the direction of a nerve axon by using an anodic electric current, in contrast to the cathodic current used in the transcutaneous electrical stimulation of the past methods.
