electro-wetting
n.— «In other application fields, so-called liquid lenses have been known for some time. In these, the application of electrical voltages causes a shape change of the liquid lens and therefore a change in its focal length. The underlying physical effect is also referred to as “electro-wetting.”» —“Intraocular lens description/claims” by Christof Donitzky, Klaus Vogler FreshPatents.com May 17, 2006.
