It is impossible to see when the "lead" in a pencil cracks within the pencil, but an acoustic sensor can "hear" the change in the way the pencil vibrates. Now, researchers in China have reported in the International Journal of Sensor Networks how the same principle can be used to detect cracks in oil pipelines components in remote regions where extreme conditions can lead to corrosion, damage to welds and pipe alike.
