    Abstract: An accelerometer (10) having a piezoelectric transducer (22) which produces electrical signals in response to its deflection and comprises an elongated, continuous beam of generally flat configuration and narrow cross section to provide a bending axis which facilitates deflection of the free ends in response to shock in one or more of the linear and torsional modes. The beam is supported intermediate its ends by a mount (29), with the free ends of the beam preferably extending equidistantly in opposite directions from the mount. By laminating a single piece of piezoelectric material to a rigid substrate and forming cantilevers in each deflection direction, an accelerometer with six degrees of freedom may be formed. Also, a compressive type angular accelerometer (122) may be formed from two piezoelectric sensor elements incorporated onto a single piece of piezoelectric polymer (126).
