Abstract:
A microaccelerometer device for indicating an acceleration event comprising:a substrate having a surface plane;a first cantilever formed from a material layer deposited on said substrate and having a fixed end and a free end, the fixed end being anchored to said substrate, said first cantilever having a mass affixed thereto;latch means formed from a material layer deposited on said substrate for unlatching said first cantilever in a first position thereof and, for latching said first cantilever when the free end of said first cantilever has moved to a predetermined position, to indicate an occurrence of an acceleration event;conductor means coupled between said latch means and said first cantilever for enabling dispatch therefrom of a signal indication of a latched state or an unlatched state of said first cantilever; andstop means positioned to confront said mass for controlling unwanted movement of said first cantilever in a direction opposite to a direction of the movement being read out.
