Contributions à l’intégration de capteurs radiofréquences de gaz imprimés sur substrats souples

Abstract : The Internet of Things is undergoing an exceptional development that is likely to bring about a major change in our lifestyles in the coming years. In this context, many markets, such as gas sensors, want to integrate this revolution. However, the different technologies of these sensors with a high Technology Readiness Level are incompatible with the needs of the Internet of Things, such as low energy consumption. Thus, one of the proposed solutions is the development of passive radio fre-quency technology since it has many advantages such as its very low remote energy consumption, its reversibility at room temperature, or its low manufacturing cost. The objective of my thesis is to design and integrate new RF transducers for the detection of volatile and harmful chemical species. Thus, the first chapter of this manuscript highlights the reasons explaining the need to be able to detect and measure specific gases as well as the different existing sensor technologies. The second chapter presents the design studies and also the characterizations of the materials used. Finally, a third and last part explains the measurements carried out under gas and humidity as well as the methods used to carry out the data processing.
