Abstract

In this work, we utilize ferrofluids deposited atop an ultra-high permeability Metglas® (Fe85B5Si10) amorphous thin film coated micromachined quartz resonator (μ-QCR) array as a unique magnetometer introduced by our group for the first time to the best of our knowledge. The magnetometer employs magnetoviscous effect of ferrofluids i.e. external magnetic field induced variations in the viscosity of a ferrofluid emulsion. The μ-QCR array detects these viscosity changes by virtue of its high sensitivity to viscoelastic changes in adsorbed films on its electrode. Initial measurements on the device has shown promising results, where it was possible to detect magnetic field inputs as low as ∼60 nT with a SNR of 3:1.
