THREE-COMPONENT PIEZOELECTRIC VIBRATION ACCELEROMETER PROVIDED WITH A SENSOR

摘要

The inventive device comprises a piezo element, embodied in the form of a square based rectangular parallelopiped fixed to a substrate. A piezo module matrix is embodied in a given shape. A conductive layer is made of a conductive glue. The edges of said rectangular parallelopiped are devoid of said conductive layer which is embodied in the form of a rectangle on each side face. For each side face, a charge is picked-up at one point which is located in the area of one of angular points of the conductive rectangle of the side face. The substrate is embodied such that it is conductive. The square base is fixed to the substrate by use of a conductive glue which is also used for the conductive layer.
