Consumer electronics are becoming more and more network embedded and added to/with conventional electronics and functions, for example in the automotive sector.

Data transmission happens either electrically or optically. In the case of electrical, high-frequency data transmission, the surrounding dielectric plays a role in addition to the electrical conductor, since charge transport in high-frequency fields takes place only in the outermost region of the conductor (skin effect) and reduces cross-talk between conductors. Surrounding insulation materials with a low dielectric permittivity are therefore advantageous for good data quality.

The material developments therefore enable improved data transmission qualities in many electronic applications in the high-frequency range, especially in components where the developed material can be used as an insulating layer.

In addition, materials have also been developed at CeSMA that can be used as polymer optical fibers and in opto-electronic assemblies for data transmission. Using a special laser process, the optical path can also be defined after the opto-electronic components have already been assembled.
