Strain gauges is the most common device for measuring strain. Since the electric resistance of strain gauge changes only a little, strain gauges are almost always used in a bridge configuration with a excitation source. In this study, a strain measuring method, which calculate strain by reading a resistance of strain gauge, are investigated and verified.
