"super-strain barium calcium zirconium titanate, high piezoelectric charge constant d33 ≈7500 pm V-1, order magnitude greater... eco-friendly... simple synthesis process: soft-templating using sol-gel-based diblock copolymer pore-director... opens up new possibilities for developing and applying ferroelectric devices in energy harvesting. With high efficiency in energy harvesting, these innovative devices are expected to become rivals to traditional energy sources like coal and hydrocarbons in the future"
