Performance Characteristics

The displacement of the larger piezoelectric bending actuators was measured by
placing an actuator under an Olympus SZHlO research stereo microscope
(www.olympusamerica.com). The microscope was focused on a thin piece of wire glued
to the tip of the actuator since the actuator itself is wider than the focal length of the
microscope, and a transparent scale bar 2 mm in length with 10μm intervals was placed
under the wire. The wire added a negligible amount of length. A Nikon Coolpix 5000
digital camera (www.nikonusa.com) was mounted on the microscope. First an image of
the scale bar was taken, and then photographs were captured of the actuator being
