1 Ltd has developed a new type of actuator called Helimorph, that uses PZT piezoelectric materials that have been layered into a helix, separated with conducting electrodes. When voltage is applied the free end moves parallel to the axis of the major helix, resulting in large (several millimeters) of displacement, whereas conventional piezoelectric materials move on the order of microns.

Researchers at Purdue University are using a neural network to identify noise and vibration problems on automobiles. A large part of the program involves characterizing the noise and vibration signals from various sub-systems, such as exhaust system, power train, suspension etc, with their associated faults such as floor vibration, cavity boom etc. The work is being funded by ArvinMeritor, a large automotive systems and parts supplier.
