An accelerometer according to claim 8, wherein the means for determining bending stress on the inner spring members comprises two piezoresistors on each of the inner spring members, one at each end of each spring member. 10. An accelerometer according to claim 7, wherein the inner spring members and the outer spring members are oriented at substantially 45° to one another. 11. An accelerometer according to claim 7, wherein the inner mass is supported by two pairs of inner spring members, arranged such that each pair is perpendicular to the other, and both pairs of inner spring members and the axis of the outer spring members are coplanar. 12. An accelerometer according to claim 8, wherein the means for determining bending stress on the inner spring members comprises a piezoresistor at one end of each inner spring member. 13. An accelerometer according to claim 8, wherein the means for determining the bending stress on the inner spring members is positioned either on one or both of the pairs of inner spring members adjacent to the inner mass or outer mass. 14. An accelerometer according to claim 8, wherein the means for determining the torsion stress comprises a Wheatstone bridge formed from four piezoresistors, each of the piezoresistors arranged on the outer spring member or members substantially along a single direction. 15. An accelerometer according to claim 7, wherein one of the outer spring members is longer than the other. 16. An accelerometer according to claim 8, wherein the means of detecting bending and torsional stress is piezoelectric. 17. An accelerometer according to claim 1, further comprising a third means of independently detecting rotational and translation movements by capacitive detection. 18. An accelerometer comprising: a housing including a mass-supporting frame; a mass supported on the frame; support means for supporting the mass on the frame; means for detecting rotation of the mass with respect to the support means; means for detecting translation of the mass with respect to the support means; and an upper casing separated from the mass by a gap, wherein a fluid or gas is located in the gap between the casing and the upper mass to provide mechanical damping, wherein the mechanical damping is controlled by forming a recess in the upper surface of the mass. 19. An accelerometer comprising: a housing including a frame; a mass supported on the frame, wherein the mass includes a first section supported on the frame for rotational movement about a first axis, and a second section supported on the first section for movement along a second axis, the second axis being substantially perdendicular to the first axis; means for detecting rotation of the mass about the first axis; and means for detecting movement of the mass along the second axis. 20. The accelerometer of claim 19, wherein the first section of the mass is supported on the frame by a pair of first support members that extend between the frame and the first section of the mass along the first axis. 21. The accelerometer of claim 20, wherein the second section of the mass is supported on the first section via second support members arranged in a plane that includes the first axis, wherein each second support member extends between the first and second sections of the mass. 22. The accelerometer of claim 19, wherein the first section of the mass defines an open area within which the second section of the mass is located. 23. The accelerometer of claim 20, wherein the mass defines a center of gravity that is offset from the first axis in the direction of the second axis, such that a force applied to the accelerometer along a third axis perpendicular to the first and second axes causes the mass to rotate about the first axis.
