Abstract

A liquid lens system is devised by actuating the contact angle of a 3 μL liquid droplet over an Alumina ITO-coated glass substrate via electrowetting. Introduction of a voltage potential of up to 31 V across the coating changes the hydrophobicity of that layer. This causes a change in the shape of the liquid droplet. Because the shape of the liquid droplet is dictated by the amount of voltage potential, the focal length of the liquid lens system will also depend on the applied voltage. This study has potential applications in miniaturized systems like miniaturized cameras and lab-on-a-chip systems.
