  • Redox stimulated variable-modulus material
    Patent number: 10894846
    Abstract: A material having a first non-zero elastic modulus capable of reversibly changing the first non-zero elastic modulus to a second non-zero elastic modulus in response to a redox reaction occurring in the material. A method of producing a material that is reversibly cyclable between a first non-zero elastic modulus and a second non-zero elastic modulus, comprising: preparing a polymer comprising both crosslinks that do not depend on metal binding and functional groups capable of having oxidation-state specific binding constants to a metal ion; and doping the polymer with a solution containing the metal ion.
    Type: Grant
    Filed: December 2, 2016
    Date of Patent: January 19, 2021
    Assignee: University of Pittsburgh—Of The Commonwealth System of Higher Education
    Inventors: Tianqi Pan, Tara Yvonne Meyer, William W. Clark, David Waldeck, Lisa Mauck Weiland, Percy Calvo-Marzal, Rachel D. Harris, Haitao Liu

  • ADAPTIVE HYDROKINETIC ENERGY HARVESTING
    Publication number: 20140001761
    Abstract: An energy harvester for producing useable energy from fluid motion of a fluid medium, the energy harvester comprising a support structure affixed directly or indirectly to a foundation or mounting; wherein the support structure comprises one or more legs; a morphable moving element movably supported by the support structure for oscillating movement along an axis of the support structure, wherein the axis is substantially perpendicular to a direction of the fluid motion; a biasing element or spring for biasing the morphable moving element in a first direction along the axis; and a converter for converting mechanical energy of the morphable moving element to useable energy.
