Linear Control Ring 20 MPa Piezoelectric Ceramic Actuator

100 Billion Cycles – Can an Actuator be Designed to Provide this Kind of Reliability!

1. Ceramic-insulated, cofired high-performance piezo stacks outlast polymer-insulated types

The short answer is yes. However, before the advent of monolithic, cofired and ceramic encapsulated piezo actuators, the reliability of piezo ceramics was strongly dependent on the environmental conditions at the site of application. For actuators with conformal coatings, humidity, temperature and operating voltage are of considerable influence, since no polymer insulation exists that is absolutely impermeable. For these devices the life expectancy can decrease dramatically at high humidity. Ingressing moisture and the electric field applied can then cause chemical reactions in the component, which are accelerated by higher temperature. The result is initially an increased leakage current and finally a dielectric breakdown, that is a short circuit between the electrodes. During dynamic operation, the service life of the piezo ceramics can be affected by dynamic forces and alternating mechanical stress conditions. Poorly designed ceramic actuators can be affected by micro cracks leading to failure quickly in such cases.
