A tuned flexure accelerometer, comprising, a housing; a gimbal coupled to the housing for oscillation about a gimbal oscillation axis; and a reference mass coupled by one or more pivots to the gimbal to allow pivoting motion of the reference mass relative to the gimbal about a pivot axis which is transverse to the gimbal oscillation axis, the one or more pivots having an effective elastic restraint. The gimbal is oscillated about its oscillation axis, to thereby induce on the one or more pivots an oscillating negative elastic restraint, to reduce the effective elastic restraint of the pivots.
