Bilayered magnetostrictive-piezoelectric composites exhibit a resonant enhancement of magnetoelectric coupling when operated under bending mode. Such composites are of importance for achieving ultrasensitive magnetometers for quasi-static magnetic fields detection by measuring the parameter variations near the resonant frequency. The detection performance is limited by diverse noise processes appearing...
This paper demonstrates a simple and cost-effective approach to separate the mechanical vibration signals from the electrical feedthrough signals resulted from stray capacitances, which is a generic issue in capacitive MEMS gyroscopes. Taking advantage of the quadratic relationship between the drive voltage and the electrostatic force, the micro-structure can be driven into resonance by using voltages...
