This project aims to design and fabricate superior eco-friendly substitutions for lead-based perovskites widely used in piezoelectric devices, to address the long-standing toxic concern of lead for human beings and the environment in the community. It is expected to surmount the fundamental limit of current approaches to reach giant room-temperature piezoelectric responses in lead-free perovskites through using a pioneering route named rare-earth doped relaxor/morphotropic phase boundary crossover. Success of this project will not only meet the Australia’s ecological sustainability goals, but also provide commercial opportunities for Australia in the large market of piezoelectric devices (> 25 Billion USD annually).

本项目旨在设计和制造上级环保替代品，以取代广泛用于压电器件的铅基钙钛矿，以解决长期以来铅对人类和环境的毒性问题。通过使用称为稀土掺杂弛豫/准同型相界交叉的开创性路线，有望克服当前方法的基本限制，在无铅钙钛矿中实现巨大的室温压电响应。该项目的成功不仅将满足澳大利亚的生态可持续发展目标，还将为澳大利亚提供巨大的压电器件市场（每年超过250亿美元）的商业机会。
