A stretchable optical sensor that can detect multiple modes of deformation and contact, including pressure, strain, and bending. The method of operation involves a waveguide and a flexible housing, in one embodiment made of silicone rubber. The interface between the two is a reflective layer that encapsulates light propagating through the channel. As the sensor is stretched, compressed, or bent, cracks within the reflective layer form and allow light to escape, resulting in a linear changes to the signal response.

A light guide system includes a substrate with multiple light sources connected to the substrate. Multiple zones are individually positioned each proximate to one of the light sources. Each of the multiple zones includes a translucent area back-lit by energizing one of the light sources. A polymeric material is applied onto individual pairs defined by one of the multiple light sources and one of the multiple zones. The polymeric material after subsequent curing defines a light guide for each of the pairs for transmission of light generated by the light source of each pair. A reflective coating is applied onto the at least one external facing surface of the light guide, the reflective coating defining a material different from the polymeric material.

A plastic reflective waveguide is manufactured using a soft transfer stamp formed in a first mold using a liquid injection molding process to provide the stamp with parallel wall surfaces having a zero degree draft angle. The soft transfer stamp is placed as an insert in a second mold utilized in a multi-stage thermoplastic injection molding process. A first thermoplastic injection molding stage molds a base part of the plastic reflective waveguide having parallel wall surfaces with a zero degree draft angle. The soft transfer stamp is removed from the second mold and a partially-reflective coating is applied to the base part. A second thermoplastic injection molding stage is utilized to create a secondary part of the plastic reflective waveguide. The raw plastic reflective waveguide is ejected from the second mold and subjected to additional manufacturing processes to realize a finished part meeting design requirements for size and form factor.
