Abstract: An accelerometer element of the bender having geometrical outside dimensions and relations wherein the height and width are alike and half of the length. The accelerometer element is built from ceramic materials and consists of two half blocks with a piezoelectric bender element clamped in-between. The high part tolerances are overcome by two fastener gaps, being filled with a special material for microcomponents. This method allows tolerance differences to be compensated by the fastener gaps and its fastening layer. The half blocks consist of a ceramic material to be ground in strips and processed with electronic components in well known batch production methods. Both sides of the blocs are protected with cover plates. The connector recess is filled with a watertight sealing material. The accelerometer element, whether with or without integrated electronics, is fully hermetic and watertight, with only the signal wires protruding on the outside.
