Publication number: 20220252564Abstract: A detection system for an electronic nose which allows a physicochemical classification of odors, that is to say a classification as a function of the physicochemical properties of the volatile compounds, or odorous molecules, making up these odors. This detection system comprises sensors with cross-reactivity with respect to volatile compounds, each sensor comprising a sensitive part functionalized by a receptor comprising a sequence formed by the repetition of an ?-amino acid. The ?-amino acid of the receptor of a sensor of a first series of sensors is hydrophilic, while the ?-amino acid of the receptor of another sensor of the first series is hydrophobic, and the ?-amino acids of the receptors of two sensors of a second series of sensors have isoelectric points which differ from one another by at least one pH unit.Type: ApplicationFiled: July 8, 2020Publication date: August 11, 2022Inventors: Yanxia Hou-Broutin, Sophie BRENET, Arnaud BUHOT, Thierry LIVACHE, Cyril HERRIER, Tristan ROUSSELLE

Patent number: 11287377Abstract: The invention relates to a detection system for an electronic nose capable of detecting and identifying a set of compounds that can be found in a gaseous sample, the detection system comprises a plurality of cross-reactivity detection sensors (D1, D2, D3, D4, D5, D6, D7) for supplying signals representing the presence of one or more compounds of said set in the gaseous sample, and which is particularly characterised in that the detection system further comprises at least one reference sensor (RI) for supplying a signal representing the measurement noise of the detection system. The detection system further relates to an electronic nose comprising such a detection system.Type: GrantFiled: September 11, 2018Date of Patent: March 29, 2022Assignees: ARYBALLE, COMMISSARIAT A L'ENERGIE ATOMIQUE ET AUX ENERGIES ALTERNATIVES, UNIVERSITÉ GRENOBLE ALPES, CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUEInventors: Yanxia Hou-Broutin, Sophie Brenet, Thierry Livache, Cyril Herrier, Tristan Rousselle

Patent number: 11085921Abstract: The present invention relates to a sensor for an electronic tongue or nose for analysing a sample or detecting a target. The sensor comprises a support, on one surface of which a plurality of sensitive areas are located, each sensitive area comprising at least one receptor and being capable of transmitting a measurable signal generated by the interaction of at least one constituent of the sample or one target with at least one receptor. The sensor is characterised in that it comprises at least three sensitive areas that differ from one another in terms of their respective receptor compositions, at least one of the sensitive areas comprising a mixture of at least two different receptors, while the two other sensitive areas each comprise at least one of the two receptors.Type: GrantFiled: February 21, 2013Date of Patent: August 10, 2021Assignees: Commissariat a l'Energie Atomique et aux Energies Alternatives, Centre National de la Recherche Scientifique, Universite Paris-SudInventors: Thierry Livache, Arnaud Buhot, David Bonnaffe, Yanxia Hou-Broutin
