Pyroelectric coefficient difference under open and short circuit conditions and their enhancements in laminate composites

Abstract

The pyroelectric coefficient is normally measured under the short circuit condition, while many pyroelectric applications are under the open circuit condition. We present experimental results demonstrating a difference in the pyroelectric coefficient under open and short circuit conditions. We also present results on pyroelectric coefficient enhancement using laminate composites, and show that this technique can enhance the pyroelectric coefficient at open circuit condition, as well as at short circuit condition.
