  • Publication number: 20230158504
    Abstract: A digital microfluidic system includes a substrate, a plurality of electrode sets provided on the substrate, wherein each of the electrode sets includes two co-planar interdigitated finger electrodes, and a driving circuit including an AC/DC voltage source and a controller. Each of the electrode sets is individually addressable by the driving circuit under control of the controller such that an AC/DC voltage generated by the AC/DC voltage source may be selectively provided to one or more of the electrode sets. Also, an anti-biofouling electrode for a digital microfluidic system includes an electrode layer, and a slippery liquid infused porous surface structure provided on the electrode layer.
    Type: Application

  • Publication number: 20190022294
    Abstract: A device hereof includes a first volume for flow of a first fluid therethrough, a second volume for flow of a second fluid therethrough, a membrane separating the first volume from the second volume, which is permeable to transfer/exchange of at least one component between the first volume and the second volume and a drive system or actuator system to induce oscillation in the membrane.
