MEMS sensor for explosives

A new method to detect explosives below their explosive limit has been developed by the University of Tennessee, ORNL, and the Technical University of Denmark.
It uses a thin silicon cantilever with integrated trackes used to both heat the cantilever and measure it's heating profile.
As the temperature profile depends on the nature of the materials condensed onto the cantilevers and is significantly different for explosives and non-explosives, it can be used to identify explosives.
