Modeling and Analysis of Hysteresis Phenomena in Electrostatic Zipper Actuators

Guidotti P., Bernstein D., California Institute of Technology, US

We investigate the relationship between the pull-in phenomenon for electrostatic actuators and the hysteresis effect found in zipper actuators. Liked lumped mass and spring and tension based membrane models, we show that a beam model [...]

Mathematical Analysis of Electrostatically Actuated MEMS Devices

Bernstein D., Guidotti P., Pelesko J.A., California Institute of Technology, US

We perform a rigorous mathematical analysis of a simple membrane based model of an electrostatiacallyh actuated MEMS device. Using both analytical and numerical techniques, we prove the existence of a fold in the solution space [...]
