A novel reagentless system for detecting airborne microorganisms and biowarfare agents is proposed (patent pending) in this paper. The system is capable of collecting and concentrating airborne agents using electrostatic precipitation (ESP), and presenting the sample to an IR spectrometer for detection. The ESP collector module is designed to provide high collection efficiencies while optimizing optical...
A new way of sensing displacement for subnanometric applications using RF resonant cavities is presented and experimentally demonstrated on a laboratory prototype. The new sensor physical principle of operation is summarized, and a first working prototype is described and tested. It is shown by experiment that very high and linear sensitivity characteristic curves, in the range of several kilohertz...
