Quartz crystal is an important electronic material. When a quartz crystal is cut in a certain direction and subjected to mechanical stress, it will produce an electric field or charge proportional to the stress. This phenomenon is called the positive piezoelectric effect. Conversely, when a quartz crystal is subjected to an electric field, it will produce a strain proportional to the electric field. This phenomenon is called the inverse piezoelectric effect. The positive and inverse effects are collectively called the piezoelectric effect. Quartz crystal not only has piezoelectric effect, but also has excellent mechanical properties, electrical properties and temperature properties. Resonators, oscillators and filters designed and manufactured with it have outstanding advantages in frequency stabilization and frequency selection.
