Qualtre's gyroscopes employ a 600-by-35 micron silicon disk resonating in the MhZ range, with just a 180-nanometer gap between it and the electrodes ringing its edge. Motion leads to a variation in vibration modes in the disk which is detected as tiny deformations in the disk as it fights the Coriolis force which is opposing its motion.

As the mechanical gain in excess of 20,000, the system uses less power, according to Qualtre. The BAW method in addition has a wider dynamic range, according to the Qualtre, making its gyroscope useful for a wide assortment of consumer applications, which also includes handheld and console based gaming controllers, navigational devices, digital cameras, camcorders and remote controls.

Qualtre is at present carrying out a second round of financing to assist bring its technology to market--its primary round of financial support being $5 million from Matrix Partners (Waltham, Mass.) and Pilot House Ventures (Boston) in 2008.
