At its core, piezoelectricity is a phenomenon where certain materials generate an electrical charge when mechanical stress is applied. Crystal piezoelectric materials, in particular, are made from specific crystalline structures that possess this unique property. The word "piezo" originates from the Greek word “piezein,” which means “to press or squeeze.” This gives us a hint about how these materials function.
When we apply pressure to a crystal piezoelectric material, it distorts the internal structure of the material, leading to a displacement of charge. This displacement creates an electrical voltage, which can then be harnessed for various purposes. Conversely, when an electric field is applied to these crystals, they can change shape, enabling movement or vibration—an essential aspect of many electronic devices.
There are several types of materials that exhibit piezoelectric properties, but some of the most common crystal piezoelectric materials include:
