Abstract

Laminated magnetoelectric (ME) composites consisting of magnetostrictive and piezoelectric layers are an important class of magnetic sensors. Here, we will present a means to design ME sensors with in-built capabilities to cancel environmental noise, based on designing the sensor signal and the noise in different fundamental modes. We then show that some composite designs offer unique capabilities to reject acoustic or thermal noise sources. (C) 2009 American Institute of Physics. [DOI: 10.1063/1.3176500]
