Piezoelectric Transducer of Acceleration

摘要

The object of the invention is a piezoelectric transducer of acceleration, which contains a piezoelectric element rigidly fastened to a body, an inertial mass and a recording apparatus. To simplify the design the piezoelectric element is made in the form of a spherical shell from a piezoceramic with a metallic external surface and this shell is filled with an electrical conducting fluid, which is simultaneously the inertial mass and the internal electrode of the piezoelectric element.
