Products	Smart skis
	These skis perform well in all conditions (in hard and soft snow). The skis use piezoelectric devices to detect the vibrations and to oppose and cancel it out. This is possible because piezoelectric materials act both as sensors and actuators. A dampening unit, consisting of three piezoelectric elements, is placed directly in front of the binding of the "smart" ski where the largest vibrations occur. Any bending of the ski causes the elements to produce a current. A logic circuit in turn induces the elements to move in opposition to the external vibrations, quickly canceling them out.
