MECHANICAL SENSOR Russian patent published in 2023 - IPC G01P15/09 

FIELD: measuring technology.

SUBSTANCE: invention is intended for the conversion of dynamic mechanical quantities. The claimed sensor consists of a cantilever type element in the form of an L-shaped support made of electrically insulating material. A horizontally located elastic metal plate with an inertial element at the other end is rigidly clamped into the vertical wall of the support at one end, and both of its surfaces adjacent to the pinch point are in contact with the electrolyte of two adjacent electrochemical cells, forming a common electrode. At the same time, the body of each of the cells is made of an elastic insulating material, one of the current-collecting electrodes is located in the upper cell, and the other in the lower one; their ends are brought out of the vertical wall of the L-shaped support. The current-collecting electrodes are made in the form of horizontally arranged elastic metal plates, identical to the common electrode, rigidly clamped at one end into the vertical wall of the L-shaped support with gaps between the plates, where U-shaped cases of electrochemical cells are placed, the horizontal edges of which are glued to the plates, and the vertical ribs - to the vertical wall of the L-shaped support, inserts of solid electrical insulating material are fixed in the gaps at the free ends of the plates.

EFFECT: increasing the sensitivity of the sensor to the effects of mechanical quantities.
