Sunlight, heat in a room and even movements may soon power your portable and wearable gadgets such as smartphones, thanks to a material identified by scientists that can extract energy from multiple sources at the same time. Researchers from the University of Oulu in Finland have found that a mineral with the perovskite crystal structure has the right properties to extract energy from many forms of energy that surround us and is normally wasted. Perovskites are a family of minerals, many of which have shown promise for harvesting one or two types of energy at a time – but not simultaneously.One member may be good for solar cells, while other my be good at harnessing energy from changes in temperature and pressure. Yang Bai and his colleagues studied a specific type of perovskite call...
