  • Capillary force actuator device and related method of applications
    Patent number: 8461949
    Abstract: An actuator capable of generates force by leveraging the changes in capillary pressure and surface tension that result from the application of an electrical potential. The device, which will be referred to as a Capillary Force Actuator (CFA), and related methods, employs a conducting liquid bridge between two (or more) surfaces, at least one of which contains dielectric-covered electrodes, and operates according to the principles of electrowetting on dielectric.
    Type: Grant
    Filed: May 14, 2012
    Date of Patent: June 11, 2013
    Assignee: University of Virginia Patent Foundation
