ACCELEROMETER OPERATING ON SHIFT DEFORMATION IN PIEZOELEMENT AND METHOD OF ITS MANUFACTURE Russian patent published in 1997 - IPC

FIELD: measuring technology. SUBSTANCE: circular piezoelement in accelerometer is cut into separate circular sectors which do not contact each other. Then circular body, polarized piezoelement and inertia mass are coupled coaxially by plastic deformation of surface of body located inside piezoelement sectors. Plastic deformation is performed by cold rolling of internal surface of body by roller or by pressing conical pin into it. In this case, body and inertia mass made of metal serve as piezoelement electrodes. EFFECT: higher efficiency. 8 cl, 3 dwg
