Pressure-sensitive sensors
First Claim
1. A pressure-sensitive sensor comprising an optical wave guide composed of core and clad each made from an elastomeric material, and a light emitting means and a light receiving means each connected to said optical wave guide, said core being transparent and having a refractive index somewhat larger than that of said clad material and being made from a synthetic rubber selected from the group consisting of chloroprene rubber, urethane rubber, silicone rubber, fluorine rubber, acrylic rubber, ethylene-propylene rubber, ethylene-propylene-diene terpolymer rubber and epichlorohydrin rubber.

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.
