Zusammenfassung Neue Entwicklungen in der Elektronik wie massengedruckte Einfachelektronik ermöglichen den Einsatz von Computersystemen an oder gar in Objekten, für die bisher ein solcher Einsatz nicht wirtschaftlich sinnvoll war. Dieser Beitrag untersucht die prinzipiellen Rahmenbedingungen bei der nahtlosen Integration von Smart Objects in bestehende IT-Strukturen. Probleme bei der Einbindung solcher Smart Objects in IT-Systeme — insbesondere hinsichtlich der Skalierbarkeit — werde thematisiert. Er zeigt zudem innovative Lösungsansätze wie “Active Interfaces” und Push der Geschäftslogik in Smart Objects. Der vorgestellte Systemansatz profitiert dabei von einer Vielzahl preiswerter, zusammenarbeitender Smart Objects und kann somit als Blaupause für die Informationsverarbeitung und Integration künftiger massengedruckter Elektroniksysteme in IT-Systeme gesehen werden. Summary New developments in electronics as simple mass printed electronics enable the implementation of computing systems at or even in objects – an application that was not economically nor technical feasible before. This paper investigates principle conditions when integrating Smart Objects seamlessly into existing IT infrastructures. We also report on problems when connecting Smart Objects to IT-Systems. Based on an implemented system, we show innovative solutions to approach this problem, namely the use of active interfaces and push of business logic to Smart Objects. The approach uses multiple Smart Objects that collaborate to perform a task. It can therefore be seen as a blue print of integrating future tiny computing systems based on printed electronics into IT infrastructures.
