MICROMECHANICAL SHOCK SENSOR Russian patent published in 2022 - IPC G01P15/08 

FIELD: measuring technology.

SUBSTANCE: invention relates to measuring technology. The micromechanical shock sensor is a normally open key having two electrodes that close when exposed to overload, a movable electrode suspended on elastic elements representing a curved beam of rectangular cross-section, fixed on one side to a fixed part of the base, and on the other side to the inertial mass, while a metal coating is applied to the inertial mass and on the lid that form the electrodes, the places of attachment of elastic elements to the inertial mass are expanded three times in area, the inertial mass has a displaced center of gravity, which makes it possible to fix overloads during lateral impacts along the X and/or Y axis and impacts at an angle to the sensitivity axis Z, the tightness of the internal working volume of the sensor is achieved by splicing the lid with the base at the place of attachment of the lid.

EFFECT: increase in impact resistance, a decrease in electrical resistance in a closed form, the possibility of multiple use of the sensor, ensuring tightness for the dynamic characteristics of the sensor.
