Researches at Warwick University and York University have
created a molecular messaging system capable of transmitting data over several
meters costing around US$100 and some vodka.
The system mimics
chemical signalling seen in nature and has potential applications for
communications in environments not compatible with conventional wireless
technologies, such as underwater, in tunnels and pipelines, as well as at the
nano scale and within the body. The first demonstration signal, performed in Canada, was “O
Canada,” from the Canadian national anthem. It was sent several meters across
open space before it was decoded by a receiver. The chemical signal, using the alcohol found in vodka in this
case, was sent four metres across the lab with the aid of a tabletop fan. It
was then demodulated by a receiver which measured the rate of change in
concentration of the alcohol molecules, picking up whether the concentration
was increasing or decreasing.
The team will
now set up a company that aims to bring a range of academic and industrial
products to the market within 6 months to 1 year.
