Monolayer
Piezoelectric products can be divided into the following segments: monolayer products with a single layer of piezoelectric material and multilayer products with multiple layers of piezoelectric materials.

Monolayer piezoceramic material is defined a product with a single layer of piezo with electrically conductive metal electrodes 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 components are manufactured by compaction of the piezoceramic powder by conventional processes like uni-axial pressing, isostatic pressing and extrusion.
Common applications for monolayer piezo products are large devices for sonar using discs, rings and plates up to several centimetres in diameter, knock sensors for automotive engines using rings approximately 2 centimetres in diameter and sensors for accelerometers using plates and tubes with dimensions less than a centimetre.
