This STTR Phase I project is to develop processes and optimized integrated structures based on the piezoelectric effect, and complemented by other traditional sources, to enable energy harvesting devices for self-powered sensors and devices. The team has recently developed a piezoelectric composition with the highest ever reported energy density for bulk piezoelectric ceramics. This project will seek to develop and optimize piezoelectric thin film processes using the newly discovered composition.Successful use of piezoelectrics for energy harvesting from vibration sources can provide a high efficiency and low maintenance power source, particularly at a small scale, for applications that are remote, inaccessible and in darkness.

STTR第一阶段项目旨在开发基于压电效应的工艺和优化的集成结构，并辅以其他传统来源，以实现自供电传感器和设备的能量收集设备。 该团队最近开发了一种压电组合物，具有有史以来最高的大块压电陶瓷能量密度。该项目将寻求开发和优化压电薄膜工艺，使用新发现的成分。成功使用压电材料从振动源中收集能量，可以为偏远、难以接近和黑暗的应用提供高效率和低维护的电源，特别是在小规模应用中。
