Grahic Jump Location
Four possible mechanism configurations for bistable micro-mechanisms. (a) is Grashof, and (b), (c), and (d) are non-Grashof.
Grahic Jump Location
An example of a bistable compliant micro-mechanism whose pseudo-rigid-body model is a non-Grashof four-link mechanism. (a) shows the mechanism and its pseudo-rigid-body model, and (b) shows the two stable positions.
