Technology is saving lives.
Sensor technology has been around for some time, but we are recently finding how diverse and incredible it can be.

On August 1, America experienced the tragedy of the I-35 bridge over the Mississippi River collapse. This event is not entirely out of the ordinary. Bridges are susceptible to fatigue and collapse over a length of time. Bridges develop hair cracks, which are immediately harmless; yet, overtime, the cracks widen and compromise the solidarity of the construction.
