A strain gauge depends on the electrical resistivity of any conductor. The resistance in any conducting device is dependent on its length as well as the cross-section area. Suppose L1 is the original length of wire and L2 is the new length after an external force is applied on it, the strain (ε) is given by the formula: ε = (L2-L1)/L1 Now

When the gauge is unstrained, the bridge is balanced, and voltmeter shows zero value. As there is a change in resistance of strain gauge, the bridge gets unbalanced and producing an indication at the voltmeter.

Optical strain sensors, explained by RP Photonics
Optical strain sensors (or strain gauges) are sensors for compressive and/or tensile mechanical strain (deformation) which are based on optical technology – in most cases, on fiber optics. They can be based on different operation principles as explained in the following. Note that mechanical strain results from mechanical forces.

Introduction to Strain Gauges and their usage
The active gauge R 1 is remote from the instrumentation, and both it and its associated wiring are subject to resistance changes brought about by any variation in temperature. In order to compensate for such changes (which the instrumentation would interpret as mechanical strain) the gauge itself should be chosen, if possible, as one having temperature compensation for the material being tested.

Strain Gages By Dr Sotiris Omirou The electrical
When strain gauges measure the changing dimensions of an object, they are measuring strain. Strain is the ratio of the change in dimension of an object to the original dimension Mechanical strain ε = ΔL / L When subject to strain, its resistance R changes, the fractional change in resistance ΔR/R being proportional to the mechanical strain i. e. Electrical strain ΔR/R= G. ΔL/L where G is

strain gauge measurements
Strain gauges can be used for (dynamic) measurements on moving components to derive mean and vibratory stress as well as vibrational characteristics, i.e. frequency response and mode shape. Strain gauges can be used with components that work in adverse environments, e.g. under water or oil. In such cases protection is applied to the gauge(s

STATIC VS DYNAMIC STRAIN GAUGE TESTING
Jul 01, 2021Static vs Dynamic Strain Gauge Testing. In most situations, the type of testing doesn't influence the choice of strain gage or adhesive. However, whether a strain gauge test is dynamic or static will affect the type of environmental protection chosen for the strain gauge. It will also affect the method of lead wire attachment and strain relief.
