Piezoelectric materials interconvert electric and mechanical energy. They have been incorporated into a wide range of industrial, medical and domestic applications. The newest, known as PZN-PTs, are only available as single crystals. They have ten times the response of conventional piezoelectric materials, however they are expensive, mechanically fragile and have shape limitations. This project will tailor nanostructured intermediate states that will allow the production of stronger, more versatile polycrystalline PZN-PT ceramics. It will develop scientific results on nanocrystalline processing applicable to many materials and allow deeper insight into the mechanism of the anomalous piezoelectric response of these materials.

压电材料可以将电能和机械能相互转换。它们已被广泛应用于工业、医疗和家庭等领域。最新的PZN-PTS只有单晶可用。它们的响应度是传统压电材料的十倍，但它们价格昂贵，机械易碎，形状有限。该项目将量身定做纳米结构中间态，从而生产出更坚固、更多功能的多晶PZN-PT陶瓷。它将发展适用于许多材料的纳米晶加工的科学结果，并使人们能够更深入地了解这些材料异常压电响应的机制。
