Invited talk: CArbon and Microwave-based Ultrasensitive gas Sensors (CAMUS)

Abstract : In the areas of safety, health and environment, the detection of chemical compounds, VOCs and toxic gases, is a major societal concern. The explosion in recent years in the telecommunications market has led to the emergence of concept of sensor network. This new concept of communicating objects meets the growing need to deploy sensors for monitoring and analysing distributed applications. These systems rely on an architecture built around wireless autonomous sensors composed of nanostructured materials that are very effective in terms of sorption of chemical compounds, and of new low cost communication electronic devices printed on flexible substrates. Thus, the research effort requires a multidisciplinary approach around the engineering of new materials, transduction mechanisms and electromagnetic waves (microwaves). The CAMUS (CArbon & Microwaves-based Ultrasensitive Gas Sensors) project is proposed by a consortium of four labs with complementary skills: IMS Bordeaux UMR 5218, XLIM Limoges UMR 7252, IEMN Lille UMR 8510, CINTRA Singapore UMI 3288 CNRS-NTU-Thales. In this project, we propose the realization of a platform for microwave transduction associated with nanostructured materials, graphene and carbon nanotubes (CNTs), allowing the extraction of interference properties of conductivity and dielectric permittivity caused by the interaction of these materials with the target species. Thus, our approach aims to demonstrate the feasibility of a passive microwave resonator on a flexible substrate dedicated to the detection of chemical compounds in the vapor state.
