Comparison of noise floor and sensitivity for different magnetoelectric laminates
We present a comparison of the magnetoelectric (ME) response and magnetic-field sensitivities of engineered laminate sensors comprised of magnetostrictive and piezoelectric phases. The ME voltage coefficients for Metglas and single crystal fibers of Pb ( Mg 1 / 3 Nb 2 / 3 ) O 3 - PbTiO 3 (PMN-PT) or...
