A group of scientists and engineers working out of the University of Huddersfield in the United Kingdom have developed a wireless warning system, designed for railway tracks, that work by drawing their power from the vibrations generated by trains when they're rolling away on railway tracks.

The sensors are capable of communicating with each other in order to form a special network, with each sensor making use of energy drawn from the vibrations made by approaching trains.The system is capable of being installed for less than $26,000 per crossing, which is a lot more economical than currently existing railway warning systems.

By making use of existing energy in the form of railway tracks, this wireless warning system boosts safety outcomes in an inventive manner.
