1. A sensorized brake pad comprising:

  • a backplate;

    a block of friction material supported by the backplate;

    a passive electrical circuit interposed between the backplate and the block of friction material, the passive electrical circuit includinga piezoelectric sensor configured to generate a sensor signal, anda passive conditioning stage configured to generate an analog conditioned signal based on conditioning the sensor signal; and

    an active conditioning stage physically separated from and thermally decoupled from the passive conditioning stage, whereinthe active conditioning stage is configured to generate an analog output signal based on processing the analog conditioned signal.
