Strain Gauges
Strain gauges are sensors that measure the strain (deformation) of an object by detecting changes in electrical resistance when the object is subjected to force or stress. They are commonly used in engineering and materials testing to monitor structural integrity, load, and stress in applications like bridges, aircraft, and machinery. These devices typically consist of a metallic foil pattern bonded to a flexible backing, which is attached to the surface being measured.
Developers should learn about strain gauges when working on projects involving structural health monitoring, robotics, automotive systems, or IoT devices that require precise force or stress measurements. They are essential in fields like civil engineering for safety assessments, in manufacturing for quality control, and in research for material property analysis, enabling real-time data collection on mechanical behavior.
