Abstract: The invention relates to a device intended to contain and dispense a cosmetic substance, said device comprising: a container that forms a leaktight volume having an orifice through which the cosmetic substance is introduced so as to be stored temporarily in said leaktight volume; a closure means for shutting off said orifice in the container; characterized in that said closure means has: a detection member for detecting actuation of said closure means with a view to taking said cosmetic substance; a communications interface for transmitting the information output by said detection member to an external data server.

Abstract: Packaging for receiving a substance having chemical properties which may change between a time when the substance is introduced for the first time into the packaging and a later time when the substance is used, the packaging including a main body; a closure member; a first sensor arranged in the main body and suitable for delivering a signal representing a measurement of a physicochemical property of the substance contained in the packaging; a display member for generating visual information representing the measurement; a processing unit for conditioning the signal delivered by the first sensor and for displaying the visual information by means of the display member; an electric power source for supplying the first sensor, the display member and the processing unit.

Abstract: A chip card for analyzing physicochemical properties of a cutaneous surface includes at least one body sensor which can deliver a signal representing a measurement of a physicochemical property of the cutaneous surface, and a processing unit used to treat signals delivered by the body sensor and an optional environment sensor and to then store signals in a storage unit on the card. An electrical energy source on the card provides electrical power to the body sensor and the processing unit.

Abstract: Device for measuring at least one physicochemical parameter of the surrounding environment, said device including at least one sensor suitable for delivering a signal representing a measurement of the physicochemical property; a display member suitable for generating visual information representing the the measurement; a processing unit suitable for conditioning the signal delivered by the sensor for displaying the visual information by means of the display member, an electric power source for supplying the sensor, the display member and the processing unit; a main body integrating the sensor; and a cap covering said sensor.
