According to the piezoelectric actuator's operating principle, when voltage is applied, the piezoelectric actuator produces a little displacement with a large amount of force.
As a result, they are utilized in a variety of applications such as ultra-precize positioning, high force handling, and force generating under fixed or dynamic settings. The Piezoelectric Injector is crucial to the operation of contemporary common rail technology. In Piezo diesel injectors, when an electrical voltage is applied, Piezo crystals slightly expand, changing their structural properties in less than a thousandth of a second. Electric potential difference between two sites is referred to as voltage, also known as electric pressure, electric tension, or (electric) potential difference. The work required to transport a unit of charge in a static electric field correlates to this.
