New Sensor To Measure Structural Stresses Can Heal Itself When Broken

Researchers from North Carolina State University have designed a sensor that can measure strain in structural materials and is capable of healing itself – an important advance for collecting data to help us make informed decisions about structural safety in the wake of earthquakes, explosions or other unexpected events.

Engineers use sensors to measure the strain, or forces, exerted on materials used to build everything from airplanes to civil infrastructure. For example, these sensors can tell us how an airplane wing is performing in flight, and give maintenance authorities advance notice when the wing may be near failure. In other words, it gives you a chance to address an issue before it becomes a problem.
