A network design that uses old TV spectrum could produce better long-range wireless connectivity. Wireless Power Harvesting for Cell Phones Nokia hopes to create a device that could harvest enough power to keep a cell phone topped up. High-Definition Video over Wi-Fi Wireless chips could soon manage a gigabit of data per second. A carbon-nanotube radio receiver can detect individual gold atoms. Researchers have made analog electronics out of carbon nanotubes. Nanoparticles can be activated by radio frequencies. Researchers have made defect-free gallium-nitride nanowires that could replace bulky quartz crystals in cell-phone receivers. A tiny radio made out of a single nanotube could find use in biological and environmental sensors. Implant it convenient but doesn't work as well as external hearing aids. To gain a better understanding of ice-sheet disintegration, Kansas researchers are building an unmanned plane with cutting-edge radar for better mapping. Research firm IMMI tracks ad exposure by sampling sound through cell phones. Is a fully implantable device worth the risks associated with the required surgery? Computing with Light and Magnets A new way of controlling light could open the door to novel optical devices. Now, owners can meet each other by swapping information between chips mounted on Fido's collar. How it influences the imaginations of technologists. [1]
