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.
The Chicago Auto Show has long been a haven for truck introductions, and this year’s edition was no exception. Chevrolet, Nissan, and Toyota all showed off new trucks, while competitors rolled out concept cars and production vehicles.
A tiny new MEMS-based reed switch may enable engineers to reduce the size of the electronic circuitry in devices ranging from ingestible endoscopes and hearing aids to insulin delivery systems and brake fluid monitors.
