Imagine a lens for your camera phone that is very small and has no moving parts yet is still able to focus and zoom like the “huge” lens you already have.  French startup Varioptic has come up with a technology that makes zoom lens elements which have been shrunk down to a couple millimeters in size… but they say they’ll go smaller.

The technology is very cool.  They sandwich a couple of liquids of similar density into their element and move the edges of the liquid “bubble” by applying electrostatic pressure.  The surface tension forces the shape to bulge, focusing the element.  Clever.

Now maybe that Dick Tracy watch can really have a video phone!
