Piezoelectricity, also referred to as the piezoelectric effect, is the ability of a material to generate a voltage and/or an electrical signal (noise) when subjected to an external mechanical stress or vibration.
Synonymous with the term “microphonics”, MLCCs constructed of ferroelectric materials are piezoelectric in nature and can convert external stress, similarly to the way a microphone converts sound, into an electrical signal.
