Purdue University researchers have designed wearable acoustic emission sensors that could be used to monitor the formation of microcracks that can lead to hairline stress fractures in bones. The goal of the device is to alert users when a stress fracture is imminent so that they can stop potentially damaging physical activity. Purdue researchers say they hope the technology can be used to protect race horses, as well as soldiers, athletes and dancers.

Commenters doubted the manufacturers, describing them as H-1B visa promoters, corporate crybabies, and clowns. They argued that US manufacturers aren’t willing to train workers, preferring instead to import cheap labor from abroad.
Using wireless chips and accessories, engineers can now extract data from the unlikeliest of places -- pumps, motors, bridges, conveyors, refineries, cooling towers, parking garages, down-hole drills and just about anything else that can benefit from monitoring.
