A Novel EWOD Digital Microfluidic Device Using P(VDF-TrFE)

摘要：

A novel digital microfluidic device using the high dielectric constant material P(VDF-TrFE) (poly-vinylidene fluoride-trifluoroethylene) as the dielectric layer fabricated by spin-coating process is proposed. The device is featured with the advantages of both low driving voltage and IC compatible process. The dielectric constant of P(VDF-TrFE) is measured as high as 11.6. The contact angle between the liquid droplet and the device changes from 118° to 75° under an applied voltage of 30V. A droplet of 3μL PBS (phosphate buffered saline) has been successfully driven reciprocatively on the planar surface under an operating voltage of 20V.
