Utilizing a procedure known as electro-wetting, a water drop is saved on a metal substrate and secured by a slim protecting layer. At the point when a voltage is connected to the metal, it changes the edge of the fluid drop.
The fluid lens is contained two fluids, water and oil, one is a conductor while the other is a separator. A variety in the voltage causes a change to the shape of the fluid to fluid interface, which changes the central length of the lens.
The utilization of fluids takes into account minimal effort development. There are no moving parts and electrical utilization is to a great degree low. The lens has an extensive backwards central length range, snappy reaction, high optical quality and can work in a wide temperature range.
