Strain Sensor

      A strain sensor, also known as a strain gauge, is a device used to measure the deformation or strain of an object when subjected to an external force. Strain gauges operate on the principle that a material's electrical resistance changes in response to mechanical deformation. As the material stretches or compresses, the strain gauge detects these changes and converts them into an electrical signal, which can then be analyzed to determine the amount of strain.

      Structural health monitoring (SHM) is an area of growing interest and worthy of new and innovative approaches. The United States spends more than $200 billion each year on the maintenance of plant equipment and facilities. Maintenance and repairs represent about a quarter of commercial aircraft operating costs. Out of approximately 576,600 bridges in the US national inventory, about a third are either “structurally deficient” and in need of repairs, or “functionally obsolete” and in need of replacement. The mounting costs associated with the aging infrastructure have become an ongoing concern.

      The increasing age of our existing infrastructure makes the cost of maintenance and repairs a growing concern. Structural health monitoring may alleviate this by replacing scheduled maintenance with as-needed maintenance, thus saving the cost of unnecessary maintenance, on one hand, and preventing unscheduled maintenance, on the other hand. For new structures, the inclusion of structural health monitoring sensors and systems from the design stage is likely to greatly reduce the life-cycle cost. Structural health monitoring systems could ensure increased safety and reliability while reducing maintenance costs.
