Zusammenfassung Es werden zwei Sensortechnologien für den Einsatz zur Dehnungsmessung in adaptronischen Systemen vorgestellt. Inhomogen dotierte, piezoresistive Siliziumelemente und gedruckte Sensorschichten werden hinsichtlich ihrer Sensoreigenschaften verglichen. Die zum Verständnis nötigen Grundlagen beider Sensortechnologien werden erläutert. Neben dem statischen Übertragungsverhalten wird auch das Rauschen der Sensoren untersucht.Summary Two sensing technologies for realizing strain sensors, which can be integrated into adaptronic systems, are presented. Inhomogeniously doped silicon chips based on the piezoresistive principle and printed strain sensors are compared. The operating mode of each sensor type is explained. The static characteristics and the noise as one of the main internal error sources are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
