Digital Approaches on Frequency Tuning for Magnetoelectric Sensors

2022 29th IEEE International Conference on Electronics, Circuits and Systems (ICECS), 2022
Magnetoelectric sensor concepts typically require magnetic or electrical excitation signals with a specific frequency and amplitude for operation. These required signals present a challenge in terms of the necessary frequency accuracy to enable ME sensors operation at their particular resonance frequency.

Comparison of reference sensors for noise cancellation of magnetoelectric sensors

2016 IEEE SENSORS, 2016
Thin-film magnetoelectric (ME) sensors offer a promising potential to measure biomagnetic signals in the near future. Unfortunately, this sensor type shows usually a large cross-sensitivity to all kinds of mechanic distortion due to the resonant structure. In order to overcome this problem several sensor designs have been proposed.

Electrically modulated magnetoelectric sensors

Applied Physics Letters, 2016
Magnetoelectric thin film composites have demonstrated their potential to detect sub-pT magnetic fields if mechanical resonances (typically few hundred Hz to a few kHz) are utilized. At low frequencies (1–100 Hz), magnetic field-induced frequency conversion has enabled wideband measurements with resonance-enhanced sensitivities by using the nonlinear ...

Magnetoelectric sensors for biomagnetic measurements

2011 IEEE International Symposium on Medical Measurements and Applications, 2011
Magnetoelectric sensors are assumed to be capable of biomagnetic measurements like magnetoencephalography (MEG) and magnetocardiography (MCG). In this paper a thin film sensor with a ME coefficient of α ME = 450 V/cmOe at a resonance frequency of f res = 678.5 Hz is investigated.

High-temperature multiferroic magnetoelectric sensors

Applied Physics Letters, 2022
Magnetoelectric (ME) sensors are an important tool to detect weak magnetic fields in the industry; however, to date, there are no high-quality ME sensors available for high-temperature environments such as engines, deep underground, and outer space. Here, a 0.364BiScO3–0.636PbTiO3 piezoelectric ceramic and Terfenol-D alloy with a Curie temperature of ...

Low damping resonant magnetoelectric sensors

Applied Physics Letters, 2010
The signal of magnetic sensors based on resonant cantilevers comprised of elastically coupled piezoelectric and magnetostrictive materials increases as the damping decreases. Here, we demonstrate that air damping which normally is suppressed by evacuation can also be substantially reduced by lowering the resonance frequency.

Magnetoelectric sensor for non-destructive testing

Automation. Modern Techologies, 2022
An original design of a magnetoelectric sensor for non-destructive testing (MSFNDT) is presented. A comparative analysis of the MSFNDT operation is carried out and the advantages in terms of technical and economic indicators are shown. A mathematical model with further theoretical calculations and analysis of the obtained analytical expressions with ...

Magnetoelectric sensor excitations in hexaferrite films

Applied Physics Letters, 2015
We developed techniques for H- and E-field sensors utilizing single phase magnetoelectric (ME) hexaferrite thin films in the frequency range of 1 kHz to 10 MHz. The technique incorporating solenoid coils and multi-capacitors bank was developed to probe the physics and properties of ME hexaferrite film and explore ME effects for sensor detections and ...

Magnetoelectric position sensors for automotive application

2017 15th International Conference on Electrical Machines, Drives and Power Systems (ELMA), 2017
In this paper it is proposed to use magnetoelectric material as the sensing element of position sensors for car. Proposed ME position sensor has several advantages against the traditional one such as smaller size and weight. Magnetostrictive-piezoelectric layered structure based on PZT and Metglas was used as sensor. The designed sensor showed the peak
