摘要： Waveguides, such as light guides, made entirely of elastomeric material or with indents on an outer surface are disclosed. These improved waveguides can be used in scissors, soft robotics, or displays. For example, the waveguides can be used in a strain sensor, a curvature sensor, or a force sensor. In an instance, the waveguide can be used in a hand prosthetic. Sensors that use the disclosed waveguides and methods of manufacturing waveguides also are disclosed.

摘要： A waveguide is provided. The waveguide having a first core, a second core spaced apart from and parallel with the first core, and a cladding surrounding the first core and the second core. An interstitial portion of the cladding is located between the first core and the second core. A first region of the first core adjacent to the cladding or of the cladding adjacent to the first core is color dyed.
