Liquid Lens for your Camera Phone
"Why do good cellular telephones fall for bad digital cameras? Blame the lenses. Unlike the optics on a full-featured camera, phonecam lenses are static, shoved into a product with neither the space nor budget for variable focus or zoom. Unless your subject is in the camera's sweet spot - the distance at which its focus is fixed - your picture will be blurry. In contrast, the ideal optical setup would be small, soft, and adaptable, like the human eye. So cell phone makers are salivating over liquid lenses, tiny gadgets that suspend a drop of liquid in an electrostatic field. Change the field and the shape of the droplet changes, too, altering how the light bends when it passes through - just like a lens."
A little water and electricity will improve the quality and optical zoom of all these camera phones? It sounds a little far fetched to me. Why haven't I seen this in any of those super small digital cameras?
