1 NIPPON CERAMIC Co., Ltd. Pyroelectric Infrared Sensor . NICERA .. The pyrosensor, as developed and supplied to the market by NICERA, is being used world wide for many applications. For example, light switch control, visitor acknowledgement, security systems and burglar alarms. Utilizing our expertism gained by years of state of the art expertise, we satisfy marketing needs for high quality and low cost. Principle of Operation .. Material call ferroelectrics absorb thermal energy which changes spontaneous polarization generating a surface electrical charge. The charge is proportional to polarizarion change. This phenomenon is called the Pyroelectric effect. A pyrosensor using fine ceramic materials can detect even the slightest Infrared energy charge, such as that from a human body.. Infrared Floating electric charge .. Temp change .. Polarization change . Thermal equilibrium condition Immediately after temp change [ ] [ ].
