Technology: Liquid Camera Lens

Varioptic has invented a lens which uses a mixture of oil and water based fluids to focus, much like the human eye. The level of electrostatic current controls the mix, and the result is autofocus and optical zoom with no moving parts. Though the technology was announced 2 years ago, it has been unavailable to manufacturers until last week. The media has focused primary application in cameraphones; I envision how this may revolutionize surveillance equipment. From www.gizmodo.com
