Exploration of lead free ferroelectric crystals for transducer applications

该项目旨在研究无铅晶体，该晶体有望具有用于医学成像和水下声学的高压电性能，作为有毒铅基铁电体的替代品，该铁电体主要用于超声换能器。该项目将对开发具有理想性能的新型无铅铁电晶体产生重大影响。这将通过提供晶体生长的知识和技术使澳大利亚工业受益，从而使先进的超声换能器能够用于医学成像和水下声学应用。

This project aims to investigate lead free crystals, which are expected to possess high piezoelectric properties for medical imaging and underwater acoustics, as an alternative to toxic lead-based ferroelectrics which have been dominantly used in ultrasound transducers. The project will have significant impact on development of new lead-free ferroelectric crystals with desirable properties. This will benefit Australian industry by providing knowledge and technology of crystal growth, enabling advanced ultrasound transducers for medical imaging and underwater acoustic applications.
