Paper Abstract

The study shows an analysis of numerical models of MEMS transducers used for magnetic field measurements. Movable silicon microbeam structures attached from one side were considered. A ferromagnetic NiFe layer was deposited on the microbeams’ surfaces by magnetron sputtering. In a magnetic field, there is a torque acting on a beam with NiFe layer. There is a change in a deflection angle of a free end of the beam according to the magnetic field strength. The impact of the beam parameters and its attachment on the deflection was analyzed for the tested numerical models of the transducers. An optoelectronic test system can be used to measure the beam’s end deflection. Experimental characteristics obtained from a test system for rotation angle transducers were shown. Range of measurements corresponds to the tested models.
