Patent ID: 7500406

Claim:
A multiaxial sensor having a plurality of multiaxial sensor units for measuring one or more of two or more-axial force, moment, acceleration, and angular acceleration, externally applied, the plurality of multiaxial sensor units being disposed on a same plane and disposed around a center point of the multiaxial sensor at 90 degree intervals at the same distance from the center point, each of the multiaxial sensor units comprising: eight strain gauges disposed on a single plane; one bridge circuit constructed by connecting the strain gauges; and a strain generation body comprising a force receiving portion provided at a center, a fixed portion provided on an outer circumference, and an annular diaphragm portion connecting the force receiving portion and the fixed portion to each other; wherein the strain gauges being disposed at four positions on outer and inner edges of the diaphragm on a line perpendicular to a center line of the diaphragm, and at four positions on the outer and inner edges of the diaphragm on a line perpendicular to the line perpendicular to the center line of the diaphragm; and each of the strain gauges is a piezoresistive element or a strain gauge formed by sputtering.
