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. 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. A new gadget can broadcast music from your iPod to friends nearby. How it influences the imaginations of technologists. [1]
