摘要: Abstract The work investigates alternative capacitive sensing topologies for microelectromechanical systems, that simultaneously enable large quasi-stationary sensitivity, comparable to parallel-plates configuration, and quality (Q) factor. In agreement with the model predictions, about 3-fold larger Q factor 2-fold resonant sensitivity are obtained on optimized geometry.
