Abstract
Failures due to thermal issues are common in high power piezoelectric devices. This Measurement Good Practice Guide aims to give engineers an understanding of the problems, where they occur and how to avoid them. The guide covers ways and methods to predict the temperature rise seen, based on simple analytical models and the use of Finite Element Models. It reviews all the previous methodologies that people have used, and introduces some new techniques, applying them in a series of case studies that embody most of the conditions that are seen in real systems. The thermal property data needed for the thermal models, such as specific heat capacity and thermal diffusivity are measured, along with a summary of findings by other workers.
