Spiral coil enhancing tactile sensation in tracing on tiny undulation surface

Abstract

In this study, a new device which amplify user’s tactile sensation in tracing on tiny undulation has been discovered. The device is a thin and slender flat spiral coil. Also, the amplification factor is quantitatively evaluated using a strain gauge mechatron sand. In this experiment, the designed tactile plate is traced in two states with and without a coil with the mechatro sand, and a signal from the sensor device at that time is acquired. The coil proposed in this paper is 1/5 times thinner than the tactile contact lens and 1/5 times smaller in width. In addition, considering the length of the pin, it was found from the experiment result that there is an amplification factor more than twice that of the tactile contact lens.
