    Abstract: Methods and equipment for determining conditions of adhesion between a first and a second mechanical element are disclosed. The mechanical elements are attached respectively to a first and second support, which are immersed in an electrolyte together with a counter-electrode and a reference electrode to form an electrochemical cell. The second mechanical element is a working electrode being connected to an insulated electric wire that is also connected to the counter-electrode. A first uncovered face of the second element is pressed against the first element. A potential is applied to the second element of at least one predetermined value and/or a predetermined electrical current. The method can include detecting the electrical current that is transmitted through the electrolyte as a function of the potential applied and/or the potential that is established as a function of the predetermined current.

    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: 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.
