Patent number: 11906422Abstract: The invention relates to a device for detecting a gaseous species by photoacoustic effect. The device comprises a substrate, inside which a cavity is formed. A light source is disposed on the substrate, in such a way that a part of the substrate extends between the light source and the cavity. The device is arranged in such a way that the light, emitted by the light source, is propagated through the substrate, before reaching the cavity.Type: GrantFiled: November 25, 2022Date of Patent: February 20, 2024Assignee: Commissariat à l'Energie Atomique et aux Energies AlternativesInventors: Emmanuel Ollier, Caroline Coutier, Laurent Duraffourg, Thierry Verdot
