Abstract

Previous reports to this SPIE forum have described a new generation of passive infrared (PIR) security sensors based on silicon microbolometer MOEMS technology. The technology is now patented and under development for commercial exploitation. This paper extends the PIR sensor analysis to smaller microbolometer size. This has been motivated by the availability of MEMS foundries offering high resolution lithography, hence smaller feature size. The performance of sensors with 10 and 25μm microbolometer size is given and compared with previous results. The flexibility of the technology to meet different applications is discussed.
