Title (EN) OFET-BASED ETHYLENE GAS SENSOR
(FR) CAPTEUR DE GAZ ÉTHYLÈNE CONTITUÉ D'UN TEC ORGANIQUE
Abstract:
(EN) An ethylene gas sensor based on an organic field-effect transistor that includes an organic semiconductor layer incorporating a non-conducting polymer. The non-conducting polymer enhances the response of the organic field-effect transistor to presence of ethylene.
(FR) L'invention concerne un capteur de gaz éthylène constitué d'un transistor à effet de champ organique qui comprend une couche semi-conductrice organique contenant un polymère non conducteur. Le polymère non conducteur améliore la réponse du transistor à effet de champ organique à la présence d'éthylène.
