From this... that! Basic research to bridge sensors

 

Mehdi Kalantari Khandani at the University of Maryland has created a sensor system that constantly monitors different types of stresses on bridge structures and, when it detects anything unusual, alerts those who need to know. But Khandani's initial research had nothing to do with bridges or sensors. This is the story of how Khandani's basic research on ultra-low-power sensor networks ultimately led to low-maintenance bridge sensors that can help keep an eye on the structural integrity of our bridges.
