The misalignment of lateral combdrive fingers was studied using analytical and finite element techniques. Using the principle of virtual work, the required driving force, and the forces and moments that develop during in-plane combdrive misalignment were theoretically calculated. Electrostatic uncoupled 2-D and 3-D finite element models were then used to perform energy computations during misalignment. Finally, a stability analysis of misaligned combdrive fingers was performed using a coupled 2-D finite element approach. The analytical and numerical results were compared and found to vary due to fringing in the electrostatic fields. The significance of the fringing fields and stability equilibrium states were subsequently discussed with respect to the precision of MEMS devices.
