STRAIN GAUGE AND STRAIN SENSOR HAVING THEREOF

摘要

Provided in the present invention are: a strain gauge, capable of increasing the lifespan by preventing the breakage or cracks in a portion with a great strain rate, and obtaining the optimized measurement results by arranging a curved sensor optimized in a strain range of each of the measurement portions in the measurement target having the various strain ranges. According to an exemplary embodiment of the present invention, the strain gauge composed of silicon comprises at least one bent and formed curve unit which is a rod shape.
