Günter Hans Sauerbrey (January 1, 1933 – May 15, 2003) was a German

physicist A physicist is a scientist who specializes in the field of physics, which encompasses the interactions of matter and energy at all length and time scales in the physical universe. Physicists generally are interested in the root or ultimate caus ...

Research contributions

Günter Sauerbrey invented the

. He developed the research related to QCM in his doctoral thesis at the

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 The Sauerbrey equation was developed by the German Günter Sauerbrey in 1959, while working on his doctoral thesis at the Technical University of Berlin, Germany. It is a method for correlating changes in the oscillation frequency of a piezoelect ...

to explain the working principle of the device. Later, other authors developed derivative equations for different cases.
