Abstract: Various braking devices, systems, and methods are disclosed. In some embodiments, the braking device includes a support element, a block of friction material supported by the support element, at least one piezoceramic sensor supported by the support element and interposed between the block of friction material (and the support element, and a protective element located at the piezoceramic sensor and embedding the latter. The protective element can have one or more layers of resin-based material applied to protect the piezoceramic sensor and direct a predetermined part of the external compression force onto an area of the support element surrounding the piezoceramic sensor. In some embodiments, a signal transduction device is provided and includes at least one piezoceramic sensor supported on a support element and has an integral protective coating having properties of mechanical and temperature resistance.

Abstract: The invention concerns a method of manufacturing a module intended to create a portable object with chip and antenna. The portable object comprises an antenna and a chip placed on an insulating substrate. The antenna comprises a plurality of turns. The method comprises a first step in which an insulating substrate with at least one side is provided. The method is characterised in that it further comprises a second step in which an individual housing opening in the said side is made for each of the said turns and a third step in which said antenna comprising a plurality of turns is made by placing a conducting material in each individual housing.

Abstract: The invention concerns a method of manufacturing a module (24) intended to create a portable object with chip and antenna (36). The portable object comprises an antenna (20, 20a, 20b, 20c) and a chip (18) placed on an insulating substrate (10). The antenna (20, 20a, 20b, 20c) comprises a plurality of turns (14). The method comprises a first step in which an insulating substrate (10) with at least one side (10′) is provided. The method is characterised in that it further comprises a second step in which an individual housing (12, 12a, 12b, 12c) opening in the said side (10′) is made for each of the said turns (14) and a third step in which said antenna (20, 20a, 20b, 20c) comprising a plurality of turns (14) is made by placing a conducting material (20a, 20b, 20c) in each individual housing (12, 12a, 12b, 12c).
