A new sensor system being developed at the University of Missouri-Rolla may help get rescue personnel to the scene faster the next time a tornado or terrorist damages a bridge or other structure because of its ability to “memorize” the location of the damage.
Unlike all other infrastructure-embedded sensors, which reset following the disaster, the distributed cable sensors under development at UMR could “memorize” the most severe damage that occurred during a prior catastrophic event, allowing for an immediate assessment of the structure’s performance and integrity.
“This is critical to making a rapid decision for emergency responses and evaluations immediately following the catastrophic event,” says Dr. Genda Chen, associate professor of civil engineering at UMR. “The current practice requires sending an engineer inspector to every bridge along the emergency vehicle route to get into the striking area to rescue people. In the future, you could use a hand-held piece of equipment to detect whether there’s damage or not. We can detect the location and severity of damage areas within two inches.”

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...
