After successfully text messaging 'O Canada' using evaporated vodka, two
"Chemical signals can offer a more efficient way of transmitting data inside tunnels, pipelines or deep underground structures. For example, the recent massive clog in
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.
"We believe we have sent the world's first text message to be transmitted entirely with molecular communication, controlling concentration levels of the alcohol molecules, to encode the alphabets with single spray representing bit 1 and no spray representing the bit 0," says York U doctoral candidate
Though use of chemical signals is a new method in human communication technology, the biocompatible method is very common in the animal kingdom. Bees for example use chemicals in pheromones when there is a threat to the hive, and so do the Canadian lnyx, when marking territories.
In an article, Tabletop Molecular Communication: Text Messages Through Chemical Signals, in the peer-reviewed journal PLOS ONE, the researchers say their system also fills a major gap in the molecular communication literature, by providing an inexpensive platform for testing theoretical models. This allows researchers to gain real-world experience with molecular communication, cheaply and easily.
"Our system shows that reliable communication is possible and our work motivates future studies on more realistic modelling, analysis, and design of theoretical models and algorithms for molecular communication systems," says Engineering Professor Weisi Guo at the
