Abstract: A brake element is sensorized by at least one piezoceramic sensor arranged between a metallic support element and a block of friction material of a brake element, the sensor being completely embedded within the block. An electrical voltage signal generated by at least one piezoceramic sensor, without the need for a power supply, is picked up by an electrical circuit integrated into the metallic support element. The electrical voltage signal is processed in the form of equal length of samples per unit of time of the detected signal by successively processing in real time each sample of equal length of time sample of the signal by applying an algorithm. The algorithm is selected from at least one of a sequence of integrations of voltage values in the sample carried out in an interval of time in the order of milliseconds; FFT voltage data sample; and integral of the voltage data sample.

Abstract: Various machines, systems, and methods for generating calibration data for a sensorized brake pad are disclosed. In some embodiments, a system includes a fixture, a brake pad retainer, a pressure plate, an actuator and a controller. The actuator applies a pressure to the sensorized brake pad and signals from the pressure sensors are received. Calibration data is generated based on the signals received from the pressures sensors when the pressure is applied to the sensorized brake pad.

Abstract: A method in which at least one piezoceramic sensor and an electric circuit to collect an electric signal emitted by the piezoceramic sensor when subjected to a mechanical stress and possibly processing it are made as an electrically insulated unit. The unit is equipped with at least a branching ending with respective electric contacts and having the connected at least one piezoelectric sensor. The electric circuit and the at least one sensor are mechanically fixed integral with a first surface of a supporting metal element of a brake pad. Branching is formed so as to position the at least one piezoelectric sensor at a predetermined point of the first surface.
