Name of the project : Development of a micro-sensor for the detection and analysis of bio-aerosols

Type of project : PhD


Poor indoor air quality, whether in private homes or in public establishments, can cause asthma, allergies or other lung conditions. Air quality can be degraded by the presence of suspended particles from outdoor air or from the propagation of mold and/or bacteria in confined spaces.

There is currently no device capable of monitoring or characterizing bio-aerosols to monitor sensitive individuals (asthmatics, etc.) or to regulate building ventilation systems in the event of confinement in real time and in situ. This research project is a continuation of two theses in collaboration with the CSTB, CERTES (Center for Study and Research in Thermal, Environment and Systems) of the University of Paris-Est Créteil Val de Marne (UPEC), and ESYCOM/ESIEE on the development of a mass particle micro-sensor for analyzing air quality from a particle pollution standpoint.

In continuing with this initial work, CSTB is proposing a thesis in collaboration with CERTES and ESIEE to develop a sensor that can specifically detect the presence of polluting particles commonly found in indoor environments.

The doctoral student will join the CSTB Health-Comfort department, as well as the CERTES aerosol physicist team and the ESIEE microelectronics team for specific periods.

The objective of this thesis is to study functionalized and/or micro/nanostructured surfaces with a view to developing a micro-sensor specific to certain polluting particles.
