Randy Atkins:  A brick-size device would be attached to key places on bridges.  Tony Nanni, a University of Miami engineer, says they could monitor structural integrity for seven years without a battery change and point to urgent concerns.

Randy Atkins:  Using lasers and other sensors, Nanni says they'd detect changes in cracking, stiffness, and more.
