Résumé

In this paper we will illustrate our studies on photoacoustic spectroscopy based on mechanical resonators (Quartz tuning forks and MEMS) and their application on breath analysis. We will describe a several-months measurement campaign at Montpellier Hospital, which focused on diagnosing chronic heart failure using Quartz Enhanced Photoacoustic Spectroscopy (QEPAS).
