Semiconductor pressure sensors have limitations when used in hot environments. One of the most debilitating limitations is their susceptibility to electromagnetic interference. A new self-calibrated interfermetric intensity-based (SCIIB) sensor developed at the Virginia Tech Photonic Laboratory (VTPI) is immune to electromagnetic interference. It also resists chemical corrosion and withstands temperature above 482C—the temperature limit of sensors used in jet engines, power plants, and other hot environments. Sensors placed in a jet engine are expected to monitor sound pressure waves and warn the pilot about potential engine problems. The sensors are made using the fibers of a single crystal sapphire. The U.S. Department of Energy awarded VTPI's partner, Oak Ridge National Laboratory, with funding to collaborate on the project and commercialize the sensors. Oak Ridge National Lab has a sapphire material processing and fabrication facility. For information call (540) 231-4363.
BMW has already incorporated more than 10,000 3D-printed parts in the Rolls-Royce Phantom and intends to expand the use of 3D printing in its cars even more in the future. Meanwhile, Daimler has started using additive manufacturing for producing spare parts in Mercedes-Benz Trucks.
Researchers have been developing a number of nano- and micro-scale technologies that can be used for implantable medical technology for the treatment of disease, diagnostics, prevention, and other health-related applications.
SABIC's lightweighting polycarbonate glazing materials have appeared for the first time in a production car: the rear quarter window of Toyota's special edition 86 GRMN sports car, where they're saving 50% of its weight compared to conventional glass.
