Open Optoelectrowetting Droplet Device

Summary

Researchers at Purdue University have developed an open wetting technology that works better than the standard open wetting technology, especially for addressable multi-droplet manipulations. This technology includes a photoconductor, a special layout of coplanar electrodes, and an insulator on a substrate, which allows simultaneous multi-droplet manipulation and leaves the top space for more flexible integrations. By using coplanar electrodes to form an equivalent circuit loop on the bottom substrate, an electrostatic force prompts the liquid droplet to wet the hydrophobic surface.
