Embodiment Construction

[0096] The microelectrode array structure is applicable to other digital microfluidics technologies such as dielectrophoresis (DEP) based technologies, but for discussion purposes below, various embodiments of the invention will be described using EWOD technology.

[0097] EWOD-based devices are commonly used to manipulate droplets by exciting them with interfacial tension gradients across the gap between adjacent electrodes. The design of the electrodes includes the desired shape, size of each electrode and the gap between each two electrodes. In droplet manipulation based on EWOD-based LOC layout design, the droplet path is usually constructed by multiple electrodes connecting different regions of the design.

[0098] exist Figure 1AA conventional electrowetting microactuator structure is shown in (shown on a smaller scale for illustrative purposes only). The EWOD-based digital microfluidic device includes two glass plates 120 and 121 parallel to each other. The bottom pl...

Abstract

The invention discloses a microelectrode array architecture, concretely a device of the microelectrode array architecture, comprising: (a) a bottom plate comprising an array of multiple microelectrodes disposed on a top surface of a substrate covered by a dielectric layer; wherein each of the microelectrode is coupled to at least one grounding elements of a grounding mechanism, wherein a hydrophobic layer is disposed on the top of the dielectric layer and the grounding elements to make hydrophobic surfaces with the droplets; (b) a field programmability mechanism for programming a group of configured-electrodes to generate microfluidic components and layouts with selected shapes and sizes; and, (c) a system management unit, comprising: a droplet manipulation unit; and a system control unit.
