Dynamic trapping experiment in an elctrostaticlly actuated initially curved beam

We report on a first experimental demonstration of dynamic trapping of electrostatically actuated double clamped curved micro beam. The beam is configured in an isolated singular post-buckled configuration, showing enhanced gap usage which cannot be reached by either static or by a suddenly applied single step load. The trapping is achieved using a dynamic snap-through induced by a tailored two step time dependent electrostatic loading.
