description: This paper describes the route, from simulations toward experiments, for optimizing the  magnetoelectric (ME) geometries for vortex magnetic field sensors. The research is performed on the  base of the Metglas/Piezoelectric (PZT) laminates in both open and closed magnetic circuit (OMC and  CMC) geometries with di�erent widths (W), lengths (L), and diameters (D). Among these geometries,  the CMC laminates demonstrate advantages not only in their magnetic flux distribution, but also in  their sensitivity and in their independence of the position of the vortex center. In addition, the ME  voltage signal is found to be enhanced by increasing the magnetostrictive volume fraction. Optimal  issues are incorporated to realize a CMC-based ME double sandwich current sensor in the ring shape  with D � W = 6 mm � 1.5 mm and four layers of Metglas. At the resonant frequency of 174.4 kHz,  this sensor exhibits the record sensitivity of 5.426 V/A as compared to variety of devices such as the  CMC ME sensor family, fluxgate, magnetoresistive, and Hall-e�ect-based devices. It opens a potential  to commercialize a new generation of ME-based current and (or) vortex magnetic sensors.
