There is provided a vibrational energy harvester comprising: a frame, a flexure assembly coupled to the frame, the flexure assembly comprising a flexure configured to flex in a first direction relative to the frame and a mass fixed to the flexure, wherein when the mass is displaced in the first direction from a rest position, the flexure provides a restoring force on the mass to bring the mass back to the rest position, and a transduction assembly configured to convert movement of the mass and flexure into electrical energy, wherein the frame comprises a cavity positioned so that, if the mass is displaced in the first direction beyond a threshold distance, a portion of the flexure assembly extends into the cavity so that compression or restriction of fluid in the cavity applies an additional force on the flexure assembly.
