Wear and tear on Humvees need not slow down the U.S. Army – soldiers could soon drive over speed bump-like diagnostic cleats to determine the conditions their vehicles are in.
Embedded sensors could detect suspension or tire problems by comparing vibration signatures with the baseline signature of a healthy vehicle. Researchers used triaxial accelerometers to gauge tire forces in a cleat prototype.
