Paper Abstract

Currently a carbon/glass fiber, piezoelectric-ceramic composite, LIPCA, is being investigated for use in micro aerial vehicles, micropumps, vibration control systems, and a number of bio-inspired robotic devices. Many of these applications help demonstrate the growing trend in miniaturization that drives innovative developments in products ranging from pacemakers to cell phones. When designing products for our ever shrinking world not only must the size of the principal components of the system be taken into consideration but also the components of the system that afford functionality as a bi-product of their inclusion. To this end we are referring to the mechanical or electrical systems that provide these devices with the necessary energy to perform their tasks. In order to make efficient use of LIPCA in the previously mentioned applications, the ability to forecast power consumption is essential. In the present investigation, a method of modeling the power consumption of piezoelectric devices is presented and evaluated over a range of frequencies and voltages. Effects of variation in actuator dimension, driving voltage, and frequency are presented. Accuracy of the model is assessed and factors leading to inaccuracies are identified.
