Local news station speaks with Professor Lynch about bridge safety

Toledo’s Channel 11 (WTOL) recently spoke with Professor Jerry Lynch in a segment on bridge safety.| Short Read

“The future of bridge safety could be the Interstate 275 bridge over Telegraph Road in Monroe County, with dozens of solar panels and wiring,” the WTOL website states. “The smart bridge was designed by University of Michigan Professor Jerry Lynch and his students. Its sensors measure acceleration and when trucks go over the bridge, they also collect the vibrations and the strain that the bridge is under. Lynch says that information is then sent back to Ann Arbor so they can look for signs of deterioration and damage.”

“So we collect data here daily and it gives us a complete picture of the behavior of the bridge between those periods of inspection,” Lynch told WTOL.

The electrons absorb laser light and set up “momentum combs” (the hills) spanning the energy valleys within the material (the red line). When the electrons have an energy allowed by the quantum mechanical structure of the material—and also touch the edge of the valley—they emit light. This is why some teeth of the combs are bright and some are dark. By measuring the emitted light and precisely locating its source, the research mapped out the energy valleys in a 2D crystal of tungsten diselenide.

Mapping quantum structures with light to unlock their capabilities

Rather than installing new “2D” semiconductors in devices to see what they can do, this new method puts them through their paces with lasers and light detectors. | Medium Read
