Electrowetting using an insulating layer on top of a bare electrode was later studied by Bruno Berge in 1993. [6] Electrowetting on this dielectric-coated surface is called electrowetting-on-dielectric (EWOD) [7] to distinguish it from the conventional electrowetting on the
Optoelectrowetting (OEW) is a method of liquid droplet manipulation used in microfluidics applications. This technique builds on the principle of electrowetting, which has proven useful in liquid actuation due to fast switching response times and low power consumption.
Replacing the conductor with a semiconductor results in asymmetrical electrowetting behavior (in terms of voltage polarity), depending on the semiconductor doping type and density. Incident light above the semiconductor's band gap creates photo-induced carriers via electron-hole pair generation in the depletion region of the underlying ...
In electromagnetism, a dielectric (or dielectric medium) is an electrical insulator that can be polarised by an applied electric field.When a dielectric material is placed in an electric field, electric charges do not flow through the material as they do in an electrical conductor, because they have no loosely bound, or free, electrons that may drift through the material, but instead they ...
Calcium copper titanate (also abbreviated CCTO, for calcium copper titanium oxide) is an inorganic compound with the formula CaCu 3 Ti 4 O 12. It is noteworthy for its extremely large dielectric constant (effective relative permittivity) of over 10,000 at room temperature. [1]
Using this device, material parameters such as permittivity, doping, oxide charge, and dielectric strength may be evaluated. The contact area of a mercury droplet resting on a semiconductor can be modified by electrowetting, [4] meaning that accurate parameter extraction may need to take this effect into account.
