Pilot Study: Step Width Estimation with Body-Worn Magnetoelectric Sensors [PDF]

Sensors
Step width is an important clinical motor marker for gait stability assessment. While laboratory-based systems can measure it with high accuracy, wearable solutions based on inertial measurement units do not directly provide spatial information such as ...

A one-cent room-temperature magnetoelectric sensor [PDF]

Nature Materials, 2008
The replacement of silver-palladium with nickel as an electrode material is reducing the cost of industrially manufactured barium titanate based multilayer capacitors, but nickel is magnetic. We discuss direct magnetoelectric coupling at room temperature in these one-cent multilayer capacitors, the influence of the multilayer geometry on this strain ...

Magnetoelectric nonlinearity in magnetoelectric laminate sensors [PDF]

Journal of Applied Physics, 2011
A nonlinearity in the magnetoelectric coefficient, αMENonlin, of Metglas/Pb(Zr,Ti)O3 (PZT) and Metglas/Pb(Mg1/3,Nb2/3)O3-PbTiO3 (PMN-PT) laminate sensors has been observed. This nonlinearity was found to be dependent on the dc magnetic bias (Hdc) and frequency of the ac drive field (Hac).

Application of magnetoelectric sensors in biomedicine

Journal of Physics: Conference Series, 2021
Abstract The prospects of applying highly sensitive magnetic field sensors based on the magnetoelectric effect in biomedicine are discussed in this paper. When developing highly sensitive magnetic field sensors, it is necessary to take into account the magnitude of the equivalent magnetic noise, as well as the mass and size dimensions ...
