Abstract
The present invention provides an apparatus having at least one pair of opposing surfaces formed on a support structure for movement relative to one another and an actuator operably engaging the support structure for driving the at least one pair of opposing surfaces relative to one another in response to an electrical activation of the actuator. Preferably, the actuator is a piezoelectric device. The apparatus can be adapted for clamping and/or valving applications.
