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...

The magnetic flux density change ΔB caused by the inverse magnetostrictive effect is key for achieving high-performance vibration power generation. As magnetization curve of polycrystalline Fe–47.6 at. % Co–2.3 V (Fe–Co–V) alloy became easier to magnetize applying tensile stresses, value estimated from curves depended significantly on fields. Hence, generation a U-shaped unimorph device using F...

Abstract The main aim of the present work is to investigate role Maxwell stress tensor in study active materials. Despite importance this modeling mechatronic devices used sophisticated applications, its non–symmetry still generates controversies literature, probably because classical continuum mechanics assumes a symmetric Cauchy stress, although sum and stresses non–symmetric. In framework ge...

In the framework of electromechanical energy conversion devices for vibrational harvesting, magnetostrictive materials are an attractive alternative solution to brittleness piezoelectric materials. Electromagnetic systems have low voltage output at a frequency while suitable larger bandwidth. this work, special experimental emphasis is placed on Fe80Si9B11 (also known as Metglas 2605SA1) alloy....
