Repost from MinCup24: Antimony Tin Oxide scatters the wavelengths of infrared light emitted by warm humans. The antimony is often sourced from #stibnite. This material is being used to create fabric infrared invisibility cloaks!

Room temperature objects glow with their own light (at (~10-15 micron wavelengths). If imaged objects are the same temperature, there is very little contrast and the objects are invisible! #Melexis MLX90640 from #Sparkfun.
