VOCs Detection by Microwave Transduction Using Zeolites as Sensitive Material

AbstractThe gas sensing is an environmental topic representing a strong interest for this century. Whatever the purpose: industrial emissions control or indoor quality air supervision, the challenge remains to produce effective low costs detection systems adapted to the atmospheric conditions. This study focuses on the estimation of the microwaves transduction technique viability for the toluene detection by the implementation of sensors based on zeolites layers, deposited on coplanar structures adapted to the microwave frequency range. We shall apply to explain the principles of the microwave transduction before approaching the conception of the sensors, the measurement protocol and the obtained results
