Droplet Transportation Based on EWOD Effect on a Printed-Circuit- Board (PCB) Material

Electrowetting on a dielectric (EWOD) mechanism has shown great potential to transport and manipulatecapsulated samples inside a droplet. In this research, we have described the EWOD phenomenon on a printed-circuitboard(PCB) substrate by using numerical and simulational studies. The droplet motion has been numericallyinvestigated by employing a finite element method simulation. The electrowetting mechanism has been investigated bysolving the multiphysic coupled electrostatic and droplet physics. The threshold voltage is studied for the proposedsystem. Both the effective EWOD force and droplet velocity are increased linearly by increasing the applied electricfield and the velocity of 0.2 mm/s has been achieved for 300 V electric potential.
