Researchers from the Universities of Warwick and York have developed a molecular communication system for transmitting messages through vodka. The system has been inspired by molecular signalling often seen in the plant and animal kingdom, for example; the pheromones used by insects for long-distance signalling.
Researchers for this purpose developed the capability to transform any generic message into binary signals, which in turn is programmed into evaporated alcohol molecules to demonstrate the potential of molecular communications. The first demonstration signal was performed in Canada on the Canadian national anthem, which was sent several metres across an open space before being decoded by the receiver.
The system has been made from off-the-shelf electronics which costs a meagre $100. It harbours immense potential in transmission of messages in challenging environments such as tunnels, pipelines or underwater.
