STRAIN GAUGE STRAIN SENSOR INCLUDING THE SAME AND STRAIN MEASUREMENT METHOD USING THE SAME

摘要

A strain gauge, a strain sensor including the same, and a strain measurement method using the same are disclosed. A strain gauge according to an embodiment of the present invention, a strain sensor including the same, and a strain measurement method using the same include a flexible insulating substrate, an electrode unit including a first electrode and a second electrode disposed spaced apart from each other on one surface of the substrate, and one end. Is connected to the first electrode, the other end is connected to the second electrode, and includes a sensing unit that changes electrical resistance due to deformation, and the sensing unit is formed in a length direction separated from one surface of the substrate at a predetermined interval, And a plurality of resistors having different degrees of resistance against externally applied stress, and a plurality of connectors respectively connecting the plurality of resistors to electrically connect the plurality of resistors.
