  • Waveguides for use in sensors or displays
    Patent number: 11788869
    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.
    Type: Grant
    Filed: August 31, 2022
    Date of Patent: October 17, 2023
    Assignee: Cornell University
    Inventors: Robert Shepherd, Huichan Zhao, Rukang Huang, Hedan Bai, Shuo Li
  • Waveguide and sensor based on same
    Patent number: 11614583
    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.
