Resonant core-shell magnetoelectric nanoparticles as sensors of neural magnetic activity: a computational study.

ABSTRACT: Measuring the weak magnetic fields generated by spontaneous biological activity, such as those produced in the brain or heart, offers complementary information to conventional electrophysiological techniques, as electroencephalography and electrocardiography. Nevertheless, the widespread clinical use of biomagnetic sensing is hindered by the bulky and costly technology currently available, including SQUID-based and optically pumped magnetometers. In recent years magnetoelectric materials have been explored as highly sensitive, room-temperature magnetic field sensors, offering a compelling alternative to conventional approaches. Here, we investigate the feasibility of using resonant magnetoelectric nanoparticles (MENPs) as nanoscale magnetic sensors by exploiting the delta-E effect, in whic
