Abstract

A pressure-sensitive sensor comprises an optical wave guide consisting of a core and a clad, and a light emitting means and a light receiving means each connected to the optical wave guide. The core is made from a transparent material having a refractive index somewhat larger than that of a material constituting the clad and selected from chloroprene rubber, urethane rubber, silicone rubber, fluorine rubber, acrylic rubber, ethylene-propylene rubber, ethylene-propylene-diene terpolymer rubber and epichlorohydrin rubber.
