Pyroelectric Detector Finds Application Along With Artificial Intelligence in Wearable Devices for Monitoring Social Distancing
A pyroelectric detector is a device that uses an interaction between electrically charged gases and water, in order to generate a non-contact frequency. This frequency, when coupled with the inherent energy in an electrically conductive medium, creates a detectable glow, which is detected by a pyroelectric sensor. These detectors can be used to detect both on-site sources of RF energy (such as radar) and off-site sources of EMC (including radars, microwave dishes, and passive infrared beams). Some pyroelectric sensors are designed to incorporate the concept of active phased array, in order to reduce power consumption and increase battery longevity. The pyroelectric detector is often compared to an infrared spectrometer, because it has many similarities. Both of these devices rely on a principle called the pyroelectric effect, which is the reason they both measure the same amount of the total energy that passes through a sample. However, the differences between the two instrume...
