A comparative study of integrated ferroelectric polymer pyroelectric sensors

Most of the warm blooded animals emanatethermal radiations in the MWIR to LWIR (Medium Wave toLong Wave Infrared) range from 3μm to 18μm. If the object iswarmer than the surroundings, its thermal radiation is shiftedtoward higher frequency within the band and the thermal fluxrate becomes stronger. To detect radiation in this band, singleand multi-elements pyroelectric sensors utilized in the scanningsystems to detect, with background contrast, the presence of stillor moving thermal objects emitting thermal flux in thebandwidth specified. PIR sensors are commonly used to detectthese radiation, their response is further processed by electronicsystems and generally analyzed by software embedded systems.Here we present a comparative study of commercially availablePIR sensors. In this study we evaluated dual element PIR sensorsfor their electrical and thermal parameters. Two types of testprocedures were used, which can be used for any type of PIRsensors.
