Günter Sauerbrey
Günter Hans Sauerbrey was a German physicist who invented the quartz crystal microbalance.Biography
Günter Sauerbrey obtained his Ph.D from the Technical University of Berlin. He was responsible of the Laboratory of Medical Techniques and Dosimetry of the Physikalisch-Technische Bundesanstalt in Berlin for 24 years.Günter Sauerbrey invented the quartz crystal microbalance. He developed the research related to QCM in his doctoral thesis at the Technical University of Berlin and published it in two seminals papers in 1957 and 1959. He was the first to use a harmonic acceleration field to measure mass, although he was not aware about this in the moment of publication.
Together with the quartz crystal microbalance, he developed the Sauerbrey equation to explain the working principle of the device. Later, other authors developed derivative equations for different cases.
