Abstract:
A passive, magnetic field sensor consisting of a 425 MHz surface acoustic wave (SAW) transponder loaded with a giant magnetoimpedance (GMI) element is developed. The transponder, consisting of two interdigital transducers (IDTs) and the GMI element, a multilayer structure composed of Ni80Fe 20/Cu/Ni80Fe20, are fabricated on a 128° Y-X cut LiNbO3 substrate. The integrated sensor is characterized with a network analyzer through an S-parameter measurement. Upon the application of a magnetic field, a maximum amplitude change and phase shift of 2.7 dB and 20 degree, respectively, are observed. Within the linear region, the magnetic sensitivity is 3870 dB/T and the resolution is 1.3 μT. © 2013 IEEE.
