  • Publication number: 20220395827
    Abstract: A microfluidic device includes a bottom electrode, a dielectric layer on the bottom electrode, one or more top electrodes on a region of the dielectric layer, Each of the one or more top electrodes has a sidewall that forms a sidewall angle with an outer surface of the dielectric layer that is less than 180 degrees. The sidewall of each of the one or more top electrodes and a portion of the outer surface of the dielectric layer adjacent to the sidewall define a microchannel region for transporting an open microchannel of a fluid. Such microfluidic devices may enable transport of small microchannels using low voltages.

  • Publication number: 20220220970
    Abstract: A variable impeller for a pump is proposed. The variable impeller includes a hub to which a shaft is mounted, a plurality of vanes radially arranged around the hub outward from the hub, and extension wings tightly locked to the plurality of vanes and extending length of each of the vanes. The length of the vane is adjusted in response to the pumping head that is changed by a flow rate of fluid, the pump is operated within a high efficiency section, an expensive impeller rotation speed control device is not required, and energy is reduced by reducing power consumption of the pump. In addition, during the work of changing the pumping head, the replacement of the extension wings may be quickly completed while only a part of a pump housing is opened to expose only the impeller without separating the entire assembly of the impeller from the pump.
