    This paper is about modelling and simulation of the μWalker, an electrostatic micro actuator based on stepper motion. Design optimization can be done fast and at low-cost, provided a competent model is available. The main accent lies on the modelling part of the electro-elastic plate, and on the stick-slip and beam stiffening effects. Simulations are compared to measurement results.
