1. An acceleration sensor, comprising:

  • a proof mass having opposing and alternating open and closed cells with flat surfaces adjacent to each other and separated by thin walls at cell boundaries in order to retain minimum amount of mass and to achieve maximum surface areas for maximized damping of the sensor;

    one or more dampers on both side of the proof mass to damp motion of the proof mass;

    one or more measuring supports connecting the proof mass to a frame;

    said frame connecting the sensor to a subject being measured to measure the acceleration of the subject.
