Electrowetting is a process that involves the manipulation of liquids on a solid surface using an electric field. It is based on the principle that the surface tension of a liquid can be modified by applying an electric field, which in turn changes the contact angle between the liquid and the solid surface. This phenomenon was first observed by the French physicist Gabriel Lippmann in 1875, but it wasn’t until recent years that it has been extensively studied and exploited for various applications. and solid-liquid interfaces
