    Abstract: Method for manufacturing nanoparticles comprising a metallic core coated with a layer of polymer material comprising the following steps: a) preparing a water-in-oil emulsion comprising droplets of an aqueous phase, dispersed in an organic phase, b) adding nanoparticles comprising a metallic core coated with a shell of carbonaceous material, whereby nanoparticles trapped in the droplets are obtained, c) adding precursor monomers of the polymer material, and d) adding a polymerisation initiator, adding the precursor monomers and the polymerisation initiator resulting in polymerisation of the monomers, whereby nanoparticles coated with a layer of polymer material dispersed in the organic phase are obtained.

    Abstract: The radio-frequency identification tag comprises: a ground plane made of an electrically conductive material, and an actuator made of a transducer material adapted to convert a variation of a physical quantity into a mechanical displacement of the ground plane between first and second positions when the physical quantity crosses a predetermined threshold in order to indicate this event to the reader, the transducer material being selected from a group consisting of a thermal shape-memory material, a magnetostrictive material and a magnetic shape-memory material. The transducer material is also an electrically conductive material. The ground plane and the actuator are both formed by a single strip made of this transducer material and a mobile portion of which moves relative to an antenna between the first and second positions when the physical variable crosses the predetermined threshold.

    Abstract: A radio tag capable of indicating to a reader, via a wireless link, that a variation in energy has crossed a predetermined threshold, this variation in energy being chosen from the group made up of a variation in the temperature of the radio tag and a variation in the magnetic field in which the radio tag is immersed. This radio tag includes transducer material chosen from a group made up of a thermal shape-memory material, a magnetostrictive material and a magnetic shape-memory material. This transducer material is deposited and affixed without any degree of freedom onto a substrate or an antenna of the radio tag to form, with the substrate or the antenna, a multilayer structure which flexurally deforms the antenna between a bent conformation and a less bent conformation when the energy variation crosses the predetermined threshold.
