Optoelectrowetting is a technique that merges the principles of electrowetting and optics to manipulate liquid droplets on a surface using light in conjunction with electrical fields. Electrowetting is the phenomenon where the wettability of a liquid on a solid surface can be altered by applying an electric field, effectively changing the contact angle of the droplet and allowing for dynamic control of its shape, movement, and positioning. In optoelectrowetting, light is utilized to initiate or enhance these effects.
