Your piezo partner MA NUFACTURING – tutorial This tutorial gives a basic introduction to the manufac- turing process of both monolayer and multilayer piezo products. You will find a short description of the differ- ent elements of the manufacturing process in the pro- cess flow in the section Manufacturing.

Basics on monolayer Monolayer piezoceramic material is defined a product with a single layer of piezo with electrically conductive metal elec- trodes on two opposing sides. These electrodes are used for poling the material (rectifying the electrical dipoles like in magnetic materials) and used for electrical contacts when the component is used in an application. Monolayer piezo com- ponents are manufactured by compaction of the piezoceramic powder by conventional processes like uni-axial pressing, isostatic pressing and extrusion. Common applications for monolayer components Common applications for monolayer piezo products are large devices for sonar using discs, rings and plates up to several centimetres in diameter, kn
