MEMS-based fingerprint sensors

A new ultrasound-MEMS-based fingerprint sensor has recently been presented by a company called Sonavation.

They claim the "Sonic Slide 3000" is the worlds thinnest fingerprint sensor with superb accuracy and low power requirements.
The sensor is based on a piezoceramic array with an imaging zone of 9.6mmx0.4mm creating a 256 shade geryscale image of the finger.

The applicaiton maybe questionable, with more and more fingerprint-based applications all around us, but the technology is rally interesting as there could be lots of other applications for it.
