Abstract :
We demonstrated a novel electrowetting-on-dielectric (EWOD) device for digital microfluidic using a flexible, transparent, and conducting graphene electrode. We showed that a graphene electrode had a lower leakage current and a higher breakdown voltage compared to a gold electrode when they were under the same dielectric layer such as Teflon. The droplet movement was manipulated on graphene-based EWOD using a sequential switching voltage controlled by a programmable logic controller (PLC) relay array.
