  • Electrowetting retroreflector devices, systems, and methods
    Patent number: 9122005
    Abstract: Switchable retroreflector devices that are modulated via electrowetting. The devices include an electrically-conductive polar fluid and a non-polar fluid that is immiscible with the polar fluid. The polar and the non-polar fluids differ in at least one optical property. The fluids are contained in a fluid vessel, or an array of fluid vessels. The fluids are at least partially viewable. A voltage source is configured to selectively apply an electromechanical force to the polar fluid causing repositioning and/or geometrical change of the fluids such that retroreflection in created, or suppressed, by optical refraction or by optical attenuation.
    Type: Grant
    Filed: March 17, 2009
    Date of Patent: September 1, 2015
    Assignee: University Of Cincinnati
    Inventors: Jason Heikenfeld, Murali Kilaru, Phillip Schultz, Daniel J. O'Neill
