Flextensional Actuator, Piezo Flexure Actuator

Flextensional piezo actuators (flexure guided actuators) provide maintenance free, frictionless motion. They can include
a flexure based motion amplifier to multiply the motion range of a piezo stack from typically 10's of microns to 100's
or 1000's of microns.
