Passive infrared sensors are often designed around pyroelectric materials, as the heat of a human or animal from several feet away is enough to generate a voltage. [22] Thermal Sensors: Infrared detectors, fire alarms, gas sensors, and motion sensors utilize high voltage/current responsivity. Lead-based materials (e.g., PMN-PT) excel here due ...

The Infrared Laboratory (Laboratoire InfraRouge) located within the public research institute at CEA-Leti located in Grenoble, France was established to perform research in order to develop future generations of FPAs. Sofradir was to bring these new generations of IR detectors to mature production levels. Former logo of Sofradir before LYNRED
An infrared detector is a detector that reacts to infrared (IR) radiation. The two main types of detectors are thermal and photonic (photodetectors). The thermal effects of the incident IR radiation can be followed through many temperature dependent phenomena. [2] Bolometers and microbolometers are based on changes in resistance.
In terms of the pyroelectric detector, it can be used as a sensor to support the system. Due to the unipolar axis characteristics of the pyroelectric crystal, it is characterized by asymmetry. Polarization due to changes in temperature, the so-called pyroelectric effect, is currently widely used in sensor technology.
Figure 1: [1] Thermal sensors are available in various sizes. Thermopile laser sensors (Fig 1) are used for measuring laser power from a few μW to several W (see section 2.4). [2] The incoming radiation of the laser is converted into heat energy at the surface. [3] This heat input produces a temperature gradient across the sensor.
