US Patent 7500406 Multiaxial sensor

Cost is reduced by simplifying the wiring while reducing power consumption. A multi-axis sensor unit (10) for measuring any one or more of multi-axis force, moment, acceleration and angular acceleration applied externally, comprising eight strain gauges (R11-R24) arranged on one plane, and one bridge circuit (11) formed by interlinking the strain gauges (R11-R24). As compared with a conventional multi-axis sensor unit, power consumption is reduced by decreasing the number of bridge circuits (11) and the strain gauges (R11-R24), and production cost is lowered by simplifying the wiring.
