In prior work, micro-needle electrodes were developed, however they could only stimulate the tactile receptors that located very close to the surface and therefore, they could only present stinging sensation. We developed a newly electrotactile display which has a micro-needle electrode array and a counter flat electrode. The display can stimulate all the tactile receptors, which resulted in even lower voltage required to tactile stimulation and successful display of various tactile sensation.
