Electrowetting on dielectric using graphene

摘要

An electrowetting device and a method of electrowetting may be provided. An electrode may be provided. The electrode has a graphene layer having a first side and a second side that opposes the first side. The electrode also has a dielectric layer disposed on the first side of the graphene layer. A liquid droplet is disposed on the dielectric layer. A voltage is applied through the droplet and the electrode. A contact angle between the dielectric layer and an edge of the liquid droplet contacting the dielectric layer changes in response to the applied voltage.
