The fundamental features of the detection of non-stationary undulatory perturbations of metrics based on the interference effects are considered. The advantage of the Aharonov-Bohm effect in superconductors for these purposes in comparison with the ordinary optical interference is demonstrated. Some circuitries of the interferometric detectors in order to be used with SQUID are suggested. The p...

Abstract Correctly torquing bone screws is an important factor in achieving positive patient outcomes during orthopaedic surgery. A torque-limiting smart screwdriver concept has been proposed, and ongoing work being undertaken to model the screwing process allow work. These models require experimental validation, so a test rig was developed. The magnetostrictive torque sensor this affected by m...

Magnetostriction occurs in the most ferromagnetic materials and leads to many effects [1,2]. The most useful one to refer to is the Joule effect. It is responsible for the expansion (positive magnetostriction) or the contraction (negative) of a rod subjected to a longitudinal static magnetic field. In a given material, this magnetostrain is quadratic and occurs always in the same direction what...

This paper presents a study of magnetoelectric (ME) properties the PZT/Terfenol-D composite with varying number layers. The consists piezoelectric and magnetostrictive phases that are mechanically coupled. purpose this setup is to gain control over electric polarization material via an external magnetic field. Unlike most similar composites, our samples utilize commercial patch instead pure PZT...
