The piezoelectric crystals e.g., quarts , tourmaline etc have a very special characteristics. Thin slices of these crystals develop a potential difference across the two opposite faces when subjected to a mechanical stress in a perpendicular direction. This is known as DIRECT PIEZOELECTRIC EFFECT. If the direction of the mechanical …
