Abstract:Rotational speed and temperature measurements of an engine blade surface play a vital role in the performance detection of an engine. We proposed a wireless passive LC sensor based on thick-film integration technology to integrate the sensor in situ on the surface of the rotating part, which can be used to monitor the rotational speed and temperature of the rotating part. The reflection signal generated by the impedance mismatch is output in the form of voltage through the detection circuit such that the synch… Show more
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.
