IEEE Spectrum published a general article on quantum dot potential for IR sensing, written by Invisage CTO Ted Sargent. Somehow the article does not mention Invisage. In addition Spectrum also published a video report from DEMO event explaining Invisage concept and showing its 1.1um pixel demo, including the demo board:
Another Youtube video shows Jess Lee demonstrating a wafer with sensors and a sputtering machine to make the sensing layer:
Update: Optics.org published Invisage article titled "Timer set for silicon sensor switchover".
