FIG. 1.

(a) Schematic diagram of the PZT-metglas structure. (b) ME voltage coefficient as a function of the static dc magnetic field for various PZT fiber-metglas laminate composites. The numbers indicate the number of metglas layers on both side of the PZT fiber. The inset shows the metglas-PZT thickness ratio as a function of .

Maximum ME (a) voltage and (b) charge coefficients as a function of the number of metglas layers on both sides of the PZT layer. The points show the data and the lines are drawn as a guide to the eye. Arrows indicate the maximum points. (c) Static dc magnetic field needed to achieve the maximum ME response as a function of . The solid line shows a linear fit. (d) Normalized ME voltage coefficient (ratio of the ME coefficient at a particular and the maximum ME coefficient) as a function of magnetic-electric layer thickness ratio for the present study and theoretical predictions from Ref. 12, as indicated.

(a) Calibration results for ac magnetic field as a function of voltage applied directly to the Helmholtz coils. (b) Measured voltage across the coils (blue squares) and corresponding ac magnetic field (green triangles) as a function of applied voltage across the coils and resistance in series. The solid lines indicate linear fits. (c) Lowest detectable magnetic field for the PZT fiber-metglas laminate composites as a function of the number of metglas layers on either side of PZT at 1 Hz for constant . The arrow indicates the highest sensitivity point. Representative output (d) voltage waveform for a laminate with and (e) noise level for the low noise charge amplifier as a function of real time. The corresponding magnetic field sensitivity for is also labeled in (d).
