Abstract :
This paper describes electro tactile display with micro-needle electrodes that stimulate tactile receptors using electric stimulation. The needle length was designed to have approximately the same length as the stratum corneum so as not to injure nerve area. This device allowed subjects to feel tactile sensation with lower voltage than a flat electrode array with good repeatability. In addition, the tactile sensation was created in the vicinity of the needles, i.e., tactile display with a high spatial resolution was achieved.
