Sensors of Mechanical Stresses and Deformations Based on Magnetic Phenomena

An overview of various sensors for mechanical stresses (or deformations) is provided within scope of the magnetic phenomena. The paper considers the latest achievements in the design of such sensors for the needs of smart digital devices in the area of Industrial Internet of Things applications. We specifically study the sensors based on single-domain wires, magneto-optical Kerr effect, and propagation of spin-polarized electrons.
