Thermopile thermo-sensitive element for infrared (IR) sensor array and its optimization is considered. A concept of thermal infrared sensor array based on the micro (nano)-electromechanical system (MNEMS) with nonstationary Seebeck effect is discussed. Infrared absorption of non-stoichiometric silicon nitride thin films has been studied in the region of wavenumbers 500-7500 cm −1. The estimated absorption about 64% is found for 1300 nm layer thickness, which is good enough for thermal sensor.
