Claim Text:
1. A sensor for measuring deformation caused by pressure and shearing force, the sensor comprising: a plurality of beams disposed in a lattice shape, configured to be deformed by pressure or shearing force, and having holes for wiring, wherein the holes are disposed at intersections of the plurality of beams; a strain gauge attached to each of the plurality of beams and configured to measure a deformation rate of the each of the plurality of beams which is deformed by the pressure or shearing force into the beams; a frame connected to ends of the lattice shape and disposed to surround the plurality of beams; and supports configured to support the plurality of beams at bottoms of the intersections, wherein the holes for wiring are formed through the intersections and the supports, wherein the beams have a smaller thickness than the frame, wherein the sum of the thicknesses of the intersections and the support is the same as the thickness of the frame, wherein the strain gauge is located on at least one of a top surface and a bottom surface of the beams for measuring the deformation rate caused by pressure, and wherein the strain gauge is located on at least one of both side surfaces of the beams for measuring the deformation rate caused by shear force.
