Piezo Specialist PI Releases New Paper on Piezo Actuator Lifetime and Reliability
|
|
(Nanowerk News) Piezo specialist PI (Physik Instrumente) has released a new paper on piezo actuator lifetime and reliability.
|
|
The paper describes the development and lifetime tests of ceramic encapsulated actuators in comparision with conventional polymer coated piezo actuators. Dynamic operation with a new internal electrode design for stress reduction as well as special external electrodes for high-current applications are discussed.
|
|
Several graphs enable the quick calculation of lifetime under different operational and environmental conditions.
