PIEZOELECTRIC CENTRIPETAL ACCELERATION ACCELEROMETER Russian patent published in 2023 - IPC G01P15/09 

FIELD: instrumentation.

SUBSTANCE: piezoelectric accelerometer of centripetal acceleration contains an alternating signal generator, the output of which is connected through a capacitance to a ceramic piezoelement, wherein the piezoelement is made in the form of a disk with radial polarization and with a hole in the middle, the cylindrical surfaces of which are covered with metallization, and the test mass and thickness are uniformly distributed along the outer cylindrical surface which does not exceed the radial size of the transducer, the outer surface of the piezoelectric element is connected through a feed-through capacitance to the output of the alternating signal generator and to the input of the low-pass filter.

EFFECT: ability to measure centripetal acceleration with an accelerometer.
