1. A piezoelectric accelerometer comprising:

  • a monolithic block of a ceramic piezoelectric material, said block having an outer surface;

    an electrostatic screening means coating the outer surface said monoliThic block;

    said block being provided with hollows dividing the block into parts, one part of said block serving as an inertial mass;

    another part of said block serving as a foundation;

    a third part of said block arranged between the first two said parts and serving as at least one piezoelectric element;

    said hollows thereby dividing the monolithic block into said inertial mass, piezoelectric element and foundation; and
