'Skin-tenna' wireless signals creep over human skin

dn14080-1_250.jpg A wireless antenna that channels signals along human skin could broadcast signals over your body to connect up medical implants or portable gadgets, writes New Scientist.

... The new design's ability to produce signals that creep along the skin makes it more efficient than existing battery-hungry technologies such as Bluetooth, says says William Scanlon who made the design with colleague Gareth Conway.

Signals are channelled out sideways along the skin by this reflection and the conducting plate. That makes the antenna more efficient, which could double the battery life of body-worn gadgets, Scanlon says."
