摘要（英）：

The invention provides a resistance strain gauge and a resistance strain type sensor. The resistance strain gauge comprises a flexible substrate and a resistance strain sensing unit attached to the flexible substrate. Extraction electrodes are arranged at the two ends of the resistance strain sensing unit. The resistance strain type sensor consists of a resistance strain gauge and a tested component. The resistance strain gauge and the tested component are deformed together under the effect of the physical quantity; and the physical quantity of the tested component is measured by measuring the resistance variable quantity of the resistance strain gauge during the deformation measurement process. According to the invention, 200% of maximum strain as well as the corresponding physical quantity can be measured. Moreover, the integration degree and the expansibility are high; and the resistance strain gauge and the resistance strain type sensor can be realized easily.
