Researchers from Lancaster University in the United Kingdom are working on the development of materials that would enable passing traffic to generate electricity as it uses the road. One of these so-called smart materials is called ‘piezoelectric’ ceramics. These are embedded into the road and can harvest energy via the vibrations of the passing vehicle.
In the United Kingdom, to power between 2,000 to 4,000 street lamps cost between £1,800 and £3,600 per day. If this idea of road energy harvesting technology was installed instead it would cost around 20 percent of that. Professor Mohamed Saafi, the leader of the research project, said: “This research is about helping to produce the next generation of smart road surfaces. We will be developing new materials to take advantage of the piezoelectric effect where passing vehicles cause stress on the road surface, producing voltage.”
