Abstract
A MEMS device includes at least one proof mass, the at least one proof mass is capable of moving to contact at least one target structure. The MEMS device further includes at least one elastic bump stop coupled to the proof mass and situated at a first distance from the target structure. The MEMS device additionally includes at least one secondary bump stop situated at a second distance from the target structure, wherein the second distance is greater than the first distance, and further wherein the at least one elastic bump stop moves to reduce the first distance when a shock is applied.
