Abstract: A negative stiffness apparatus includes a fluid filled bellows interposed between a first surface and a second surface wherein the bellows and the first and second surfaces have an orientation of substantial equilibrium between the first and second surfaces. The bellows and the first and second surfaces include other orientations wherein the first and second surfaces are displaced from the orientation of substantial equilibrium and the bellows exerts a displacement force to urge the first and second surfaces further away from the orientation of substantial equilibrium
