Silicon microsensor for e.g. weapon, has inertial mass and toothed wheel disposed in concentric manner such that tooth engages with toothed wheel, and elastic anchoring device limiting rotation of toothed wheel during detection of shock

摘要

The microsensor has a passive shock counting unit (3) including a support (1) and a toothed wheel (13), and a mechanical counting unit (2) displaced with respect to the support in case of shock or acceleration. An inertial mass (6) of the mechanical counting unit and the toothed wheel are disposed in a concentric manner such that a tooth (10) integrated to an arm (7) of the mechanical counting unit engages with the toothed wheel. An elastic anchoring device limits the rotation of the toothed wheel during the detection of the shock.
