The metal foil is a resistor---it conducts electricity but also resists its flow somewhat. When the sheet is bent one way it stretches the foil slightly, making it longer and thinner. This raises its resistance, since the electricity has further to go and a more constricted path to follow. On the other hand, when the sheet is bent in the other direction it compresses the foil, making it shorter and wider and lowering the resistance. Because the foil strip is so long, even slight strains will cause fairly big changes in the resistance, which will be picked up by the Wheatstone bridge.

What is the inductance of Mechanical strain gauge?
"Mechanical Strain gauges" do not have inductance. There are many types of strain gauge: Mechanical, photoelastic, electrical etc.... Are you wanting the inductance of an electrical strain gauge? if so which type?
What is a strain gauge used for and how does it work in measuring mechanical strain?
A strain gauge is a device used to measure mechanical strain, which is the deformation of an object under stress. It works by changing its electrical resistance in response to the strain applied to the object it is attached to. This change in resistance is then converted into a measurable electrical signal that can be used to determine the amount of strain the object is experiencing.
The advantage of a semiconductor strain gauge over the normal strain gauge is that?
it is more sensitive small gauge size low hysteresis
How do you increase the sensitivity of a force sensor using strain gauge?
You can increase the sensitivity of a force sensor using a strain gauge by either increasing the gauge factor (by using materials with higher sensitivity to strain) or by increasing the strain applied to the gauge (by increasing the length or width of the gauge). Both methods will increase the change in resistance of the strain gauge in response to applied force, resulting in higher sensitivity.
