EXPERIMENTAL STUDY OF THE INFLUENCE OF MASS LOADING ON THE SENSITIVITY OF A PIEZOELECTRIC SENSOR

Abstract

This study investigates the effect of applied mass loading on the response of a piezoelectric sensor during the registration of mechanical vibrations, enabling an assessment of changes in its sensitivity to vibrational disturbances. An electronic circuit was designed based on a piezoelectric sensor, a signal amplifier, and an ESP32 microcontroller. An experimental study was carried out using various mass loads to determine the sensor’s amplitude response and to establish the dependence of the output signal on the applied load mass.
