Liquid Lenses For Camera Phones: "In this article, the Register writes that 'camera phones will soon have lenses made from nothing more substantial that a couple of drops of oil and water, but will still be capable of auto focusing, and even zooming in on subjects.' The lenses, developed by the French company Varioptic, contain drops of oil and water, acting respectively as conductor and insulator, and sandwiched between two windows.

These liquid lenses could replace glass or plastic ones because of several advantages: no moving parts, leading to better reliability; a very small power consumption; very small dimensions (diameter: 8mm; thickness: 2mm); and a very fast response time of 2/100th of a second. You can expect the first camera phones using these liquid lenses as early as Christmas 2005.

These lenses might also appear in medical equipment, such as endoscopes, optical networking equipment or surveillance devices. This overview contains other details and references.
