In three-axis force sensors for forceps, the force resolution in the radial direction is worse than that in the axial direction owning to a slender shape of a forceps. This paper proposes a double diaphragm spring structure for forceps. The length between the two diaphragms can adjust the rigidity in the radial direction while it does not affect the rigidity in the axial direction. A planar spiral cutting in the cross section of the diaphragm can reduce the maximum stress applied on it. We developed a double-diaphragm spring structure for a 10 mm forceps and confirmed its isotropic resolutions in the axial and radial directions.
