The Piezo Effect and Manufacturing Processes: In this video, Dr. Patrick Pertsch, head of PI Ceramic’s Multilayer Group explains how the piezo effect works and how piezo transducers are designed and manufactured at the PI Ceramic factory. Industrial and research applications benefit from PI’s extensive know-how, experience and great flexibility in the design and manufacture of piezoelectric ceramics.
Details:
Piezo transducers utilize the special properties of the piezo-electric effect. The piezo effect occurs when a force acts on a polarized piezoceramic body and induces an electrical charge.
Conversely the body expands when an electrical voltage is applied. A great deal of experience and manufacturing knowledge of ceramic components is necessary to be able to make use of two piezoelectric properties effectively.
The production begins with the composition of the raw materials. We make our own ceramic powder and mix it according to the customer needs. The resulting spray granulate is pressed into the desired shape. There are virtually no restrictions on the variety of possible geometries.
During subsequent reworking it is possible to drill extremely fine holes and form complex contours using special machines equipped with diamond tip tools
In order to apply an electrical voltage to ceramic component it is metallized with thick or thin electrodes during an automated process
Our extensive know-how allows us to carry out further assembly steps so that our customers can use the sensitive ceramic components without any problems
In clean rooms like this the piezo components are glued and soldered carefully with high precision and mounted into metal housings finished with connecting wires, flexible circuit boards or connectors
This simplifies the integration process into the final application of the product.
Customers receive a specific custom-fit product which can be used directly in their production line for both actuator (piezo motion) and sensor applications.
Now let’s go and take a look at how products are used after delivery.
The key to success can often be found in small details even in large systems. This is how Seco uses our components for monitoring wind turbines
