Abstract

Human detects the external tactile stimulation using mechanoreceptors under the skin. There are various kinds of mechanoreceptors in the skin. In this paper, the proposed sensor mimics Ruffinis corpuscle which detects shear force. The sensor consists of Ecoflex® 0050 as a substrate and silver nanowire (AgNW) in the shape of typical strain gauge as a sensing element. The Ecoflex® 0050 was chosen as its elastic modulus is similar to that of human dermis. The sensing element is embedded in the substrate vertically for detecting shear force directly. The characterization of the sensor was carried out and it showed small hysteresis and high sensitivity (0.88 kPa -1) in the force range of 0.1 ∼ 1N.
