Abstract: A light emitting capacitor can include a first and second electrode, an electroluminescent layer, and at least one elastomeric layer. The electroluminescent layer, which can include an elastomeric material doped with semiconducting nanoparticles, can be disposed between the first and second electrodes. The elastomeric layer can encapsulate the first electrode, second electrode, and electroluminescent layer. The first and second electrodes can be hydrogel or conductive electrodes. The light emitting capacitor can provide dynamic coloration or sensory feedback. The light emitting capacitor can be used in, for example, robotics, wearables (displays, sensors, textiles), and fashion.

Abstract: 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.

Abstract: 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.
