SFB 653 – K1: Dispensed fibers for component-inherent energy transmission and optical signal coupling

The K1 sub-project contributes to the integration of an inherent information system in metallic components. The research focus is on the development of a flexible assembly and connection technology for the integration of electronic and optical components in such components.

Within the framework of the SFB 653, a component-inherent data collection and data storage as well as communication between memory and sensor or between memory and external components are realized using new manufacturing methods. For this purpose, discrete components are inserted into the component thus enabling the sensory collection of component properties, the storage of the resulting data and the transfer of the data to other components. Components made of metal are in the focus of the work, as inherent information systems currently do not exist for them. The components required for the construction of such systems fit into the geometry of the component that is adapted or prepared accordingly through cutting or forming procedures.

The aim of the sub-project K1 is to write signal lines with a selective coating directly in and on the component surfaces. To ensure high data rates even in electromagnetically disturbed environments, optical guiding structures are integrated in the component surface for data transfer. With the help of micro application procedures, optical-looking structures are dispensed. The sensors and actuators corresponding to these requirements are developed in the framework of the project.
