Abstract: The invention relates to a marking device (1) comprising an element which is made from a semi-conductor material having patterns (2-4, 12-14) which are hollowed out of the face thereof, the arrangement of said patterns being representative of at least one piece of information. The depth of the patterns (2-4, 12-14) can vary from one pattern to another and can adopt a plurality of different values which are representative of an additional piece of information. The invention also relates to an apparatus which is used to detect such marks and to articles having a marking device of said type integrated into the material forming same.

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: The device (1) has multiple patterns (2-4, 12-14) engraved on an upper face (5) of a substrate in semiconductor material e.g. silicon. The patterns have a square shape and are arranged in matrix to represent information. The patterns have variable depths that have distinct values to represent additional information. The patterns are formed by folding frustums of a pyramid. Independent claims are also included for the following: (a) an article integrating a marking device (b) a marking detection device for analyzing a marking device.
