Magnetoviscoelastic Ferrofluid-Based Magnetometer

Abstract—In this paper, we present a novel concept for magnetic sensing that is based upon the sensitive monitoring of the magnetoviscoelastic effects in magnetic nanoparticle containing ferrofluids using micromachined shear mode bulk acoustic wave quartz crystal resonators (μQCR). The unique sensor concept is based on the application of, hitherto unexplored, magnetic field induced viscoela…
