What is a wire strain gauge?

A wire strain gauge is a type of sensor used to measure deformation or strain in an object. It consists of a thin wire arranged in a specific pattern, typically mounted on a backing material, which changes its electrical resistance when stretched or compressed. This change in resistance can be measured and correlated to the amount of strain experienced by the object, making wire strain gauges valuable in various engineering and structural applications. They are commonly used in load cells, pressure sensors, and structural health monitoring.
