Additionally, some ceramic capacitors have a piezoelectric response. A piezoelectric device
generates voltage across its terminals due to mechanical stress, similar to the way a piezoelectric
accelerometer or microphone works. For a ceramic capacitor the stress can be induced by
vibrations in the system or thermal transients. The resulting voltages produced can cause
appreciable amounts of noise, especially when a ceramic capacitor is used for noise bypassing.
