      International audience ; This work presents an integrated plasmo-photonic interferometric sensor providing environmental temperature and thermo-optic coefficient measurement capabilities. By exploiting extreme light field concentration on the plasmonic metal stripe, the sensor employs a liquid dielectric layer deposited on the plasmonic sensing area for refractive index changes versus temperature. Experimental characterization was conducted with four different liquids, achieving a record temperature sensitivity of +23.86 nm/℃ for a 70% ethanol-water solution. Additionally, by leveraging the sensor's high sensitivity, the thermo-optic coefficient of an unknown liquid was determined with a relative error of 13.1%.
