A magnetoelectric (ME) bending-mode structure based on Metglas/Pb(Zr,Ti)O(3) fiber laminates has been studied. This bending mode had a fundamental resonance (FBR) of about 210 Hz, which was much lower than that of the longitudinal mode. Near the FBR, the ME voltage coefficient was about 400 V/cm·Oe. Magnetic sensors based on this bending mode had an equivalent magnetic noise floor of ≤ 0.3 pT/√Hz at f = 210 Hz.
