  • Enhanced response time of tunable optical electrowetting elements with shaped input voltage functions
    Patent number: 11493749
    Abstract: A tunable optical electrowetting element having a liquid-liquid interface shape controlled by an applied voltage. Circuitry for applying a voltage to the electrowetting element is configured to apply a shaped voltage signal comprising a first fast-rising signal combined with a second fast-rising signal. The second signal is selected to damp oscillations in the liquid-liquid interface caused by the first signal.

  • Electrowetting prism for scanning in high resolution fluorescence microscopy
    Patent number: 11226479
    Abstract: A system for high resolution multiphoton excitation microscopy is described herein. In one embodiment, the system may include an electrowetting on dielectric (EWOD) prism optically coupled to an excitation source, the EWOD prism adapted or configured to: receive a light beam from the excitation source, and project the received light beam onto a sample plane based on a tunable transmission angle of the EWOD prism, and a fluorescence imaging microscope adapted or configured to: receive a fluorescence signal from the sample plane based on the projected light beam, and relay the fluorescence signal from the sample plane to a set of detectors.
