"The NEMS Nose: Ultrasensitive Chemical Vapor Sensors based on Nanoelectromechanical (NEMS) Resonators
," Dr. Ed Myers, Caltech. More info: CMP

Abstract:
Nanoelectromechanical systems (NEMS), due to their miniscule mass, extremely high frequencies, and large compliances, are exquisitely sensitive probes of the physical world. I will discuss work in the Roukes group on using NEMS resonators as real-time chemical vapor sensors for the detection and analysis of complex gaseous mixtures, with applications ranging from defense to the life sciences. Such sensors may eventually form a vital component to a miniaturized, portable gas sensing system that retains the sensitivity and analytical power of the larger, more expensive, traditional lab-based tools. I will also discuss ongoing efforts towards enhancing the sensitivity and functionality of NEMS gas sensors by exploiting the unique properties and scaling effects of nanoscale mechanical structures.
