Paper Abstract

Stacks of RAINBOW high-displacement actuators are currently under consideration for use in scanning mechanisms capable of providing controlled travels on the order of 1 cm. In this work, actuator stacks were produced by stacking PZT-5A and PZT-5H RAINBOWs in a clamshell configuration. The displacement properties of the RAINBOW stacks were then evaluated as a function of applied electric field, static load, number of actuators in the stack, and diameter of the actuators. The displacement properties of the stacks were found to increase nearly proportionately to the number of actuators in the stack, with the PZT-5A RAINBOW stacks generating one and half to two times the displacement of the PZT-5H stacks at +/- 8 and +/- 16 kV/cm.
