Mechanical Noise Limit of a Strain-Coupled Magneto(Elasto)electric Sensor Operating Under a Magnetic or an Electric Field Modulation

Abstract

The mechanical noise limit of a strain-coupled magneto(elasto)electric composite has been investigated when a magnetic or an electric field modulation is applied to sense a low-frequency magnetic field and access dc field measurement capabilities. The sensitivity and noise of such a composite sensor were derived from constitutive equations based on the… (More)
