1. An accelerometer to measure acceleration of a body, the accelerometer compflsing:

  • (a) a supporting base;

    (b) at least one electromechanical transducer mechanically coupled lo said supporting base and operable to produce an electrical signal in accordance with acceleration of the body, said electromechanical transducer including;

    (b.1) at least one sensitive element having a sensing axis comprising at least one piezoelectric element, (b.2) at least one seismic mass positioned to apply force to said sensitive element in response to acceleration of said body to cause said piezoelectric element to generate an electrical signal in accordance with acceleration of said body;

    (c) a structural element connected to said supporting base, and (d) at least one laterally stabilizing element mechanically coupled to said electromechanical transducer and to said structural element, said stabilizing element being configured and positioned to stabilize said electromechanical transducer in a direction transverse to said sensing axis of said piezoelectric element by blocking said seismic mass from displacing in a direction transverse to said sensing axis of said piezoelectric element.
