Imagine tires that charge a vehicle as it drives, streetlights powered by the rumble of traffic, or skyscrapers that generate electricity as the buildings naturally sway and shudder.
These energy innovations could be possible thanks to researchers developing environmentally friendly materials that produce electricity when compressed or exposed to vibrations.
The energy harvesting film, which is only 0.3 millimeters thick, could be integrated into a wide variety of devices, machines, and structures, Koratkar explained. Once they synthesized their new material, which contains barium, zirconium and sulfur, the researchers tested its ability to produce electricity by subjecting it to various bodily movements, such as walking, running, clapping, and tapping fingers.
Moving forward, Koratkar's lab will explore the entire family of chalcogenide perovskite compounds in the search for those that exhibit an even stronger piezoelectric effect. Artificial intelligence and machine learning could prove useful tools in this pursuit, Koratkar said.
