Proximity Sensor Based on Magnetoelectric Material

The paper is devoted to the study of the physical foundations of the creation of proximity sensors that determine the movement of an object or the distance to an approaching object and the implementation of a proximity sensor based on the magnetoelectric effect. The developed device can measure permanent and alternating magnetic fields. To determine its capabilities and resolution, hysteresis characteristics were evaluated and measured. In addition to the theoretical description of the sensor operation, measurements were carried out. Proximity sensors detect the movement of an object or the distance to an approaching object. Magnetoelectric layered structures can be classified as multiferroid materials that combine two or more types of ordering, such as ferromagnetic and ferroelectric ordering. Magnetoelectric elements when exposed to an external magnetic field, it is advisable to use them as sensors for creating automation devices, robotics, security systems, medical equipment and automotive industry. Theoretical and practical data on the research of the proximity sensor based on the magnetoelectric effect will be presented in this paper.
