    Abstract: A method in which at least one piezoceramic sensor, which converts every mechanical force to which it is subjected into an electrical signal and having a Curie temperature higher than 200° C., is solidarized directly onto the surface of a metal support element of a vehicle braking element, which during use faces a vehicle element to be braked. While in contact with such a surface, an electrical circuit is implemented that picks up and eventually processes the electrical signal, the electrical circuit being connected with a connector integrated with the metal support element. An electrically insulating layer sandwiches the at least one piezoceramic sensor and the electrical circuit, and a block of friction material with an underlying damping layer is formed upon the electrically insulating layer. After forming the block of friction material, the piezoceramic sensor is polarized by applying a predetermined potential difference thereto by means of the connector.

    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: A vehicle braking unit comprising a support designed to be positioned in use close to an element to be braked, braking elements which are carried in a movable way by the support, actuation elements which are carried by the support for pushing the braking elements against the element to be braked and first and second guide surfaces that are integral, respectively, to the braking elements and to the support, and that cooperate together to guide and support the braking elements when they are moved towards the element to be braked by the activation of the actuation elements; the first and/or the second guide surfaces are covered by a sliding coating consisting of a polymeric resin layer with solid lubricants and/or anti-friction materials being dispersed therein, that has been cured at a temperature greater than 300° C.
