    Abstract: A metallic support of a brake pad delimited between a first and a second face, and having a perimeter edge substantially perpendicular to the first and second faces. The first face receives a block or layer of friction material, and the second face receives a dampening element. The first face has at least one projecting part extending cantilevered spaced apart from the perimeter edge so as to be completely embedded within the block or layer of friction material. The at least one projecting part is delimited at the top by a first surface upon which there is at least one first cavity filled with the block or layer of friction material. The second face has at least one second cavity forged as the at least one projecting part. At the at least one first cavity, there is at least one first relief shaped as the at least one first cavity.

    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.
