Abstract: A radiofrequency transceiver device comprises an electronic circuit including a chip and a first antenna electrically connected to the chip, a textile-core thread formed of a non-conductive material, and a second antenna formed of a textile element in an electrically conducting material and disposed in non-contiguous turns around and along the textile-core thread. The electronic circuit is disposed relative to the second antenna so as to allow the electromagnetic coupling of the first and second antenna. A label may comprise the radiofrequency transceiver device. A particular method may be used to manufacture such a device.

Abstract: The invention relates to a functional chip (100) of which at least two electrical connection pads (11a, 11b) are intended for being connected to wire elements (40a, 40b). Said chip comprises: —a substrate (10) comprising a microelectronic component electrically connected to the two electrical connection pads arranged on a front face of said substrate (10), —a cover (20) comprising a first portion (21) assembled to the front face of the substrate (10), said first portion (21) forming a spacer between the two electrical connection pads; the cover (20) further comprising a second portion (22) spaced apart from the front face of the substrate (10) and extending opposite each electrical connection pad only partially, so as to allow access to said pads, along an axis (z) normal to the front face of the substrate (10). The invention likewise relates to a method for manufacturing such a functional chip.

Abstract: The invention relates to a method for making a textile part (A; A1, A2), comprising a step of forming a stitched seam (c1, c2, c3; C). The stitched seam step also aims to secure an electronic tag (1) to the textile part (A; A1, A2). The electronic tag (1) is formed from a strip comprising a wired electronic device comprising a chip (3a) associated with at least one antenna wire (3b), the chip (3a) and the antenna wire (3b) being arranged inside the stitched seam (c1, c2, c3; C). The invention also relates to the textile part provided with the tag.

Abstract: An inkjet-printing-base process for depositing functional materials, for example PZT, on a substrate, in various instances platinized silicon. Substrate templating (via SAMs) and material deposition are both performed by an inkjet printing process. Additionally, a composition to be used as a SAM precursor ink which is a thiol in a solvent mixture, wherein the composition can be 1 dodecanethiol in a solvent mixture of 2-methoxyethanol and glycerol.

Abstract: An only inkjet-printing-based process for depositing functional materials, in various instances PZT, Bi-based material or (K,Na)-based material, on a substrate, in various instances platinized silicon. Substrate templating (via SAMs) and material deposition are both performed by an inkjet printing process. Additionally, a composition to be used as a SAM precursor ink which is a thiol in a solvent mixture. Further, a cartridge for a printing machine with such a composition. Still further, the use of such a cartridge, alone, or as a kit with another cartridge containing a precursor of the functional material, in particular to perform both steps of the printing method. Finally, a product, for instance a microsystem, obtained by the process.
