  • Publication number: 20210008557
    Abstract: Droplet interfaces are formed between droplets in an electro-wetting device comprising an array of actuation electrodes. Actuation signals are applied to selected actuation electrodes to place the droplets into an energised state in which the shape of the droplets is modified compared to a shape of the droplets in a lower energy state and to bring the two droplets into proximity. The actuation signals are then changed to lower the energy of the droplets into the lower energy state so that the droplets relax into the gap and the two droplets contact each other thereby forming a droplet interface. The use of sensing electrodes in the device permit electrical current measurements across the droplet interface. The sensing electrodes can be used for either (i) applying a reference signal during droplet actuation or (ii) recording electrical current measurements.

  • Publication number: 20200101460
    Abstract: An electrowetting on dielectric (EWOD) device includes an EWOD device array that applies electrowetting forces and contains a non-polar fluid. A barrier droplet configuration is formed using electrowetting forces to obstruct migration of a species from a first area of the EWOD device array to a protected area of the EWOD device array. A method of operating the EWOD device includes the steps of: dispensing a source droplet into a first area of the EWOD device array, the source droplet containing a migrating species, wherein the EWOD device array includes a second area to be protected from the migrating species; and forming a barrier droplet configuration positioned between the first area and the second area of the EWOD device array that obstructs a migration pathway of the migrating species between the first area and the second area.

  • Patent number: 10571426
    Abstract: A pixel circuit acts as a sensing element in a sensing device. The pixel circuit includes a sensing electrode, a first gate electrically connected to the sensing electrode, a second gate in electrical communication with the first gate, and a readout device that is electrically connected to the second gate. An input voltage applied to the sensing electrode is amplified between the first gate and the second gate, the amplification being measured as an output signal from the readout device to perform a sensing operation. For example, the output signal may be relatable to pH, analyte measurements, or other properties of sample liquids analyzed by the sensing device. A sensing device may include multiple pixels disposed on a substrate, each pixel including said pixel circuit. Driver circuits controlled by control electronics are configured to generate signals that selectively address the pixels and to read out voltages at the sensing electrodes.

  • Patent number: 6555840
    Abstract: A charge-transport structure, e g an opto-electronic structure such an electroluminescent device is manufactured by forming a uniform first charge-transport (eg electron-transport) polymer layer on a substrate. Low molar mass dyes in a solvent are ink-jet printed onto the exposed surface of the first layer to form a multicolor pattern, and the dyes are allowed to diffuse into the layer to form charge-recombination/emitter regions within the layer. Excess dyes are washed away from the surface and then a uniform second charge-transport (eg hole-transport) polymer layer is formed on the resultant smooth surface of the first layer over the tops of the regions. Finally, electrodes are deposited on the top of the second layer in registration with the regions. Photovoltaic structures and organic transistors are also disclosed.
