A strain gauge is a versatile and widely used sophisticated sensing device used to measure mechanical strain or deformation in various materials. Its importance lies in their ability to provide accurate and reliable measurements, allowing for a deeper understanding of material behavior and structural integrity. It is a fundamental component in the field of engineering and plays a crucial role in measurement of a significant amount of strain on various structures. It is an essential geotechnical tool that determines strain in a range of structures such as tunnels, underground cavities, buildings, bridges, concretes, masonry dams, embedment in soil/concrete, etc. Strain gauges are utilized in a wide range of applications, including structural analysis, load testing, material testing, and stress analysis. This paper is oriented to overview everything about the Strain gauge including working principle, characteristics, and its various applications.
