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.
When you think of the DARPA Robotics Challenge, you may imagine complex humanoid contraptions made of metal and wires that move like a Terminator Series T-90. But what actually happened at the much-vaunted event was something just a bit different.
Traditional dev kits are based on a manufacturer’s microcontroller, radio module, or sensor device. The idea is to aid the design engineer in developing his or her own IoT prototype as quickly as possible. A not-so-traditional IoT development kit released by Bosch aims to simplify IoT prototyping even further.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
