Abstract

Passive infrared detectors may be implemented at substantially lower cost with PVDF polymer than with monocrystals. Corresponding concepts have been developed at Siemens Research Laboratories and have resulted in a prototype of a passive IR sensor for detecting people as well as for automatically activating devices at the approach of people. A new sensor concept, in which the sensor is an integral component of the optical system and the electrical circuitry, exploits the negligible cost of procuring and processing large PVDF sheets. This concept allows implementation of an efficient compensation circuit which decisively reduces dead time and sensitivity to light.
