Sensing fibers for structural health monitoring

A device comprising:

• a sensing fiber that extends through a structural body, the sensing fiber to exhibit an electrical resistance that varies with deformation of the sensing fiber;
• and
• a processing unit to:
• monitor the electrical resistance of the sensing fiber;
• determine a structural strain experienced by the structural body based on the electrical resistance;
• and
• output an indication of the structural strain.
