Printed transducers embedded in polymer coatings

We provide an overview on our recent work on embedded printed transducers. This includes the description of appropriate technologies as well as technological considerations for the integration of sensors and actuators into polymer coatings, e.g., of sheet metal. In particular, the integration of capacitive large area sensors, piezo- and pyroelectric layers, and strain gauges is discussed. The devised concept has the potential to introduce additional functionality to a variety of products without the need of significant changes to associated production processes.ZusammenfassungDie Autoren geben in dieser Arbeit eine Übersicht über ihre jüngsten Arbeiten betreffend gedruckte eingebettete Messwertwandler. Sie präsentieren geeignete Herstellungstechnologien und betrachten die Einbettung von Sensoren und Aktoren in Polymerbeschichtungen, z. B. auf Blechen. Im Speziellen wird die Integration großflächiger Sensorstrukturen, piezo- und pyroelektrischer Schichten sowie gedruckter Dehnungsmessstreifen diskutiert. Das erarbeitete Konzept hat das Potential, zusätzliche Funktionalitäten in eine Reihe von Produkten, ohne signifikanten Mehraufwand in der Produktion, zu integrieren.
