The somatic sensation that results from applying stimulus to planta pedis is important to maintaining balance and walking around. In this study, we focus on the difference limens of the planta pedis to develop a new device for walking support. Experimental devices for mechanical stimulation by vibration are developed to investigate the two-point threshold level on the planta pedis. Our results clarify that the difference limens depends on the region of the planta pedis. On the basis of the result, a new actuator for reproducing continuous physical stimulation using electro-conjugate fluid is developed. In the result, we obtained the actuator for being able to keep the stimulus interval to planta pedis within a two-point threshold.
