The process chain for the series production to be developed in SFB/TR contain the supply of integrable piezo-ceramic and composite semi-finished products, the series technologies for isolation and contacting, as well as the research and design of process windows of the production technologies such as pressure die-casting, sheet forming and fiber composite for component manufacturing. For the protection of the sensor-actuator-function a research of the fundamentals is carry out for the interpretation of material composite regarding the electro-mechanical interaction of piezo-ceramic and structural material, which should clarify the interaction between the mechanical-geometrical design with the electromechanical function and the production process.

In order to expand the integration of the piezo-elements in terms of a production-ready entire process chain, that is specific for the production technology and not specially adapted for an individual component, must the technology be designed in a way which the piezo elements in the component can be used multifunctional, as well as sensor, actuator, generator or in combination all this functions. This enables, with components from the resulted multi-adaptive material compound, to achieve for example a combination of active vibration reduction and monitoring components, or to choose the desired final function of the piezo-elements through extern drive and control technology.
