Webb31 aug. 2012 · Nitinol (TiNi) based thin film SMAs are considered as a core technology for actuation of some MEMS devices, where large force and stroke are essential in condition of low duty cycles or intermittent operations, and in extreme environment, such as radioactive, space, biological and corrosive conditions [ 1, 2 ]. Webb24 mars 2015 · Nitinol, an alloy of nickel and titanium developed at the Naval Ordnance Laboratory in the 1950’s, has been widely used in medical devices because of its … WebbHeat production occurs largely due to head coil radiofrequency energy that acts on the prosthesis during all phases of MRI scanning. Heat production is amplified when an object is made with magnetic materials and when it has mass. Studies of relatively massive hip prostheses have shown no physiologically or clinically significant heating to occur. new fast movie
