A Versatile Control System for Digital Microfluidic Chips of Varying Types, Shapes, Sizes, and Thicknesses

We introduce an electronic control system developed to accelerate prototyping of digital microfluidics (DMF) devices (or chips). Designed to serve a diverse user base with different needs, this versatile control system is capable of operating DMF chips of various substrate types, shapes, sizes, and thicknesses. Constructed of a hinged pair of aluminum chassis, the USB-powered system features up to around 250 independent voltage channels and a quick-and-easy installation of various DMF chips. A graphical user interface (GUI) empowers the users to operate DMF chips with custom-designed electrode patterns.
