Autonomous driving and connected cars will stimulate a rising demand on novel sensor, harvester and energy storage systems. Besides car-to-car communication, new systems for integration of electronic components in cars need to be developed. These technologies can be basically printed and applied by robots during the paint shop. In order to circumvent the use of rare resources such as gold or silver, synthetic carbon materials such as graphene or graphene-Nanoplatelets can be used. The influence of the variation of geometrical and electrical properties of the electrode on the sensing performance will be examined. Within this research printed multilayer systems are applied directly on automotive skins, used as an invisible proximity sensor. The working principle of these sensors is based on capacitive sensing, where the distance of the object is measured by changes in the electrical field of the carbon electrode when an object approaches. To manufacture the sensors screen printing and spray coating is used. These are highly automated printing processes that can be employed into the paint shop process. In addition, this method is used due to its high productivity and reproducibility as well as realizing robust multilayer coatings. Furthermore the sensor is covered by state-of-the art automotive paint. The technology is shown by a demonstrator. During the talk the different layouts, production methods of sensors and varnish, evaluation of sensor signals and transfer to other applications will be shown.
