"Tooth-phone" provides covert chat
13:32 20 June 02 Will Knight
<a href="http://www.newscientist.com/news/print.jsp?id=ns99992436(http://www.newscientist.com/news/print.jsp?id=ns99992436">http://www.newscientist.com/news/print.jsp?id=ns99992436(http://www.newscientist.com/news/print.jsp?id=ns99992436>)

A prototype radio device designed to fit inside a human tooth and
provide covert mobile phone communications has been created by two UK
students.  The device currently consists of a digital radio receiver
that converts radio signals into sound and a tiny vibrating component,
which conveys sound to the wearer's inner ear through bone vibrations. 

Inventors James Auger and Jimmy Loizeau of the Royal College of Art in
London say the tiny receiver could be configured to receive sound from
an external device, such as a mobile phone, a radio or a computer. 

They also say it would be relatively simple to fit the gadget with a
microphone, to allow it to return a radio signal to another device. 

Sound conveyed from the tooth-phone would only be audible to the wearer,
so Auger and Loizeau believe it could have a wide range of applications. 

"At the moment were looking at commercial uses," Loizeau told New
Scientist.  "From people who want to listen to stock information to
traffic data and stock information." The device is currently wired to a
battery.  But power could be generated by an electro-magnetic
micro-generator embedded in the tooth, Loiseau suggests.  "It would be
powered as people eat, speak or wiggle their heads," he says. 

The device will be on show at the Future Products exhibition at the UK
Science Museum, London.  from 21 June to November.
