Prof Develops System to Remotely Monitor Bridges

A Clarkson University professor, operating under a state-funded research grant, has developed a system that allows for remote monitoring of bridges using a dense network of wireless sensors. The work is part of an effort to increase the way state and county departments of transportation in New York State keep track of its bridge inventory.
