Characterization and modeling of 3-D vibration modes of a micromachined u-shaped cantilever

The present work explores the potential applicability of the Lorentz force actuation of a micromachined U-shaped cantilever device for 3-D vector magnetic field measurements in a broad range of frequencies. The structures simulated are made entirely from aluminum and designed using CMOS fabrication...

description The present work explores the potential applicability of the Lorentz force actuation of a micromachined U-shaped cantilever device for 3-D vector magnetic field measurements in a broad range of frequencies. The structures simulated are made entirely from aluminum and designed using CMOS fabrication technology and bulk micromachining in CoventorWare simulation environment. Analytical models describing 3-D cantilever vibration modes that are actuated by the Lorentz force and their verification by simulation is discussed. Results show that the resonant frequencies for mode 1 and 2 increase with increasing thickness of the cantilever while it is independent of the thickness for mode 3. On the other hand the resonant frequency for mode 3 increases with increasing width of the cantilever while it is independent of width for mode 1 and 2. It is also observed that the displacement of the cantilever for identical applied Lorentz force is highest, indicated highest sensitivity, for mode 1 and lowest for mode 3. ©EDA Publishing/DTIP 2009.
