1. A sensor module comprising:
a first strain gauge including a first resistor;
a second strain gauge including a second resistor; and
a flexure element,
wherein the first strain gauge has a same characteristic as the second strain gauge, and
wherein the first strain gauge and the second strain gauge are respectively disposed toward a same surface of the flexure element, via layers each of which has a different linear expansion coefficient.
