Design and Simulation Of Uncooled Bi-material Infrared Detector

摘要

A new uncooled bi-material microcantilever detector is based on between bi-material large difference in thermal expansion and Young's modulus, having light, low cost, high sensitivity to radiation, and very matching with silicon IC technologies. A 3D microcantilever detector model had been built and simulated by ANSYS thermal-stress coupled, and gained responses to IR radiation with temperature changes, contributing to maximum deflection of geometry size.
