The Small Business Innovation Research (SBIR) Phase I project will develop high temperature piezoelectric sensors for on-line damage assessment in gas turbines. In addition to developing several promising high-temperature piezoelectric materials, the proposed work involves measurement of characteristics (dielectric constants and piezoelectric coefficients) of the promising piezoelectric materials and testing the piezelectric materials to serve as high temperature transducers. The development of high temperature piezoelectric materials and related sensors will provide a more efficient and economic diagnosis of the actual damage of turbine engine components than the past practices of relying on fixed cycles or time-intervals. The proposed technology will, therefore, significantly impact the aerospace industry where periodic inspections of turbine engine hardware are necessary to qualify engines for flight worthiness. This technology can also be used for quality control in manufacturing of high technology materials (ex: lamination in composite structures).

小型企业创新研究（SBIR）I期项目将开发高温压电传感器，以在线损伤评估燃气轮机。 除了开发几种有希望的高温压电材料外，提出的工作还涉及对有希望的压电材料的特性（电介质常数和压电系数）的测量，并测试了压电材料以作为高温传感器。 高温压电材料和相关传感器的开发将比依靠固定周期或时间间隔的过去做法更有效，更经济地诊断涡轮发动机组件的实际损害。 因此，拟议的技术将对航空航天行业产生重大影响，在这种行业中，必须定期检查涡轮发动机硬件以使引擎有资格飞行价值。该技术还可以用于制造高科技材料（EX：复合结构中的层压）。
