    Abstract: Various systems, devices, and methods for a vehicle smart brake pad comprising a sensor such as a force sensing device, and a production process thereof. For example, a production process of a vehicle brake pad can include the following steps in time sequence: applying an electrical circuit a support plate; screen printing on the electrical circuit of at least a first electrode; screen printing on the at least first electrode of a sheet of piezoelectric material; screen printing on the sheet of at least a second electrode; applying a friction pad on the support plate; and bulk polarizing the sheet of piezoelectric material by a supply of power to the at least first and second electrodes.

    Abstract: Various residual braking torque indication devices, systems, and methods are described. The devices, systems, and methods can include a sensorized brake pad. An output signal of the sensorized brake pad can be processed to provide an indication of a residual braking torque. The residual braking torque indicator can be calibrated to reference data to provide an actual measurement of the residual braking torque.

    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.
