Abstract
We propose a new proximity and tactile sensing method using capacitance measurement. The proposed sensor consists of the three electrodes (X_1, X_2, Y). The capacitance between X electrode (X_1 or X_2) and Y electrode is measured by switching between X_1 and X_2. In the experiment, detection of the object on contact and proximity, and identification of two kinds of materials on contact were demonstrated. This technique may be applicable to proximity and tactile sensor for robot and touch screen.
