Abstract

Pyroelectric infrared detectors are widely used in a host of applications, ranging from motion sensors used for people detection in intruder alarms, motion sensors, and light switches, through spectroscopic analysis equipment used in environmental monitoring to thermal imaging. There is a huge range of single crystal, polymer, ceramic, and thin-film materials that exhibit pyroelectricity. This article reviews the key properties needed from a pyroelectric material in order to get the best performance out of a device using it and compares and contrasts the different materials used and proposed for use in this application.
