Abstract

The disclosed integrated strainmeter includes substrate and strain gauges fixed on the substrate. Strain gauges are composed of three sets of dual-gate in 90 degree mode and three sets of dual-gate in shear mode alternant arranged in parallel. Each set of dual-gate in 90 degree mode and each set of dual-gate in shear mode constitute a half bridge measuring circuit. Each half bridge measuring circuit possesses a signal output end. Being connected to each other, positive pole end of each half bridge measuring circuit is connected to power source. Being connected to each other, negative pole end of each half bridge measuring circuit is connected to ground. Comparing with prior art, the invention solves issues of fussy sticking procedure, difficult to guarantee consistency of strain and too many leads, and possessing advantages of high precision, less number of leads and one time of procedure for sticking strain gauges on columniform elastic body.

Description

technical field [0001] The invention relates to a multi-dimensional force sensor strain gauge, in particular to a six-dimensional force sensor integrated strain gauge. Background technique [0002] Multi-dimensional force sensors generally adopt a compound structure with complex structure and difficult processing. Usually the elastic strain area is distributed in different planes and different regions of the elastic body, so it is necessary to paste multiple strain gauges with different numbers, and each strain gauge needs to lead out several wires, so there are the following problems: 1. Multi-dimensional The elastic body of the force sensor is complex in structure, difficult to process, and difficult to guarantee the consistency of strain; 2. The number of strain gauges pasted is large, the pasting work is heavy, and the pasting quality and pasting position accuracy are difficult to guarantee; 3. The number of strain gauge leads is large, and its connection quality and Re...
