1. A sensor for measuring acceleration in three dimensions, comprising:

  • an inertial mass and a support system for the inertial mass, said support system including a base and a plurality of support members extending between said base and said inertial mass, and sufficient in number to suspend the inertial mass in orthogonal directions and to provide a statically indeterminate structure; and

    stress sensors for measuring the acceleration induced stress in the support members thereby affording a measure of acceleration of the mass.
