Abstract

Provided is an apparatus, system and method for on-chip microfluids dispensing. The apparatus comprising a substrate; a plurality of first electrodes arranged one next to another on the substrate; a dielectric layer above and enclosing the plurality of first electrodes; and a second electrode on the substrate, wherein each of the plurality of first electrodes is in electric communication with a respective first driving signal input; wherein the second electrode is in electric communication with a second driving signal input; wherein the plurality of first electrodes define a continuous fluid path along a longitudinal direction for retaining microfluids, and wherein the second electrode is arranged within the continuous fluid path and defines a jetting position and an adjacent mixing position within the continuous fluid path.
