A spiral spring-supported proof mass for use in an accelerometer includes a plate of material having suitably high elasticity, low coefficient of thermal expansion, low magnetic susceptibility and high strength, for a proof mass. The plate has multiple spiral cuts. The spiral cuts are symmetrically disposed on a first circle of one radius and each of the spiral cuts terminate on a second, smaller circle concentric with the first circle.
