1. An electrical system for generating brake pad data for a vehicle, wherein the electrical system comprises:

  • a piezoelectric sensor configured to generate a sensor signal;

    a passive conditioning stage configured to generate an analog conditioned signal based on conditioning the sensor signal;

    an active conditioning stage configured to generate an analog output signal based on processing the analog conditioned signal; and

    a control unit configured to process the analog output signal to generate brake pad data, wherein the brake pad data comprises a digital representation of the sensor signal, wherein the active conditioning stage comprises an operational amplifier configured to buffer the analog conditioned signal.
