Strain Gage

A strain gauge is a tiny sensor used to measure how much an object stretches or compresses when forces are applied to it. When the object deforms, the strain gauge's electrical resistance changes proportionally, allowing precise detection of small movements or stresses. These sensors are commonly used in engineering and testing to monitor structural integrity, ensure safety, and improve design by providing accurate data about load and stress conditions. Their small size and high sensitivity make them essential tools for understanding how materials and structures behave under different forces.
