Chemical transmissions could transmit data where wireless signals don’t work.
Alcohol has been the motivation behind many conversations in its day, but never quite like this. Researchers at York University have used vodka to transmit a chemical message across the room using a tabletop fan and some sensors. They believe the simple system can be used where conventional wireless technology often fails.
“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 London sewer system could have been detected earlier on, and without all the mess workers had to deal with by sending robots equipped with a molecular communication system,” says Professor Andrew Eckford.
The researchers sent the message “O Canada,” which they say is the “first text message to be transmitted entirely with molecular communication.” While the idea may seem new to humans, it has long been employed in the animal world. Bees for example use chemicals in pheromones when there is a threat to the hive, and various other animals use chemicals to mark their territory.
