NANO -- World's smallest antenna . . .

Instead of the conventional long piece of metal or dipole antenna, electronic devices of tomorrow could incorporate an antenna no bigger than a gnat. This is made possible by a design that allows an electrically charged nano-mechanical oscillator to be tuned to specific electromagnetic waves. "Gone will be the days when we need to match the antenna length to the wavelength," said Panos Datskos, a co-developer of this proprietary technology. The potentially revolutionary system detects very small electric fields over large frequency ranges while maintaining substantial power efficiency, making it ideal for environmental, homeland security and electric grid applications. Other developers are Nickolay Lavrik, Slo Rajic and Thomas Thundat. [Contact: Ron Walli, (865) 576-0226; wallira@ornl.gov]

INDUSTRY -- A real steel . . .

Wireless sensors that alert steel mill operators to abnormal temperatures and vibrations that foretell wasted energy and imminent failure are expected to pay big dividends. Through the Department of Energy's Industrial Technologies Program, Oak Ridge National Laboratory has been commissioned to install and operate wireless sensors and controls to assess the energy savings of a suite of technologies, said Wayne Manges, a program manager in ORNL's Measurement Science and Systems Engineering Division. The measurements of motors and other components will be sent by secure radio signals to plant operators and archived for energy analysis. Similar technology used in the nuclear industry is avoiding down time and providing millions of dollars in savings. The steel mills involved in this project are in Braddock, Pa., and Cayce, S.C.
