Abstract0528873PI: Victor GiurgiutiuUniv. South CarolinaThe project will use nano fabrication methods (such as pulsed laser deposition) and advanced nano investigative techniques (such as SEAM, SPM, TEM, EPMA, EDS, HR-SEM, AFM, XRD) to grow miniaturized thin-film active sensor arrays on typical structural materials for use in advanced structural health monitoring applications. Appropriate buffer interfaces to ensure durable adherence of the ferroelectric film to the structural material and coherent epitaxial growth will be developed. High-performance environmentally friendly ferroelectric compositions will be developed. Modeling and analysis will be used in developing the buffered interface, the nano-fabrication processing methods, and the Lamb/Rayleigh wave phased-array algorithms for structural health monitoring applications of these new devices. The highly interdisciplinary character of the proposal is covered by a sensors small team with members from the disciplines of material science, electrical engineering, mechanical engineering, and physics, spanning over four universities (Louisiana State University, Pennsylvania State University, University of South Carolina, University of Texas at San Antonio), of which one is a Hispanic-serving institution (HSI): The project will employed analytical modeling, numerical simulation, and experimental validation. It will build on the preliminary results obtained by the individual investigators. In additional to technical activities, the project will address important sensors education and outreach activities.This is an EPSCoR research project supported under sensor solicitation NSF 05-625.

摘要0528873 PI：维克托GiurgiutiuUniv.该项目将使用纳米制造方法（如脉冲激光沉积）和先进的纳米调查技术（如SEAM，SPM，TEM，EPMA，EDS，HR-SEM，AFM，XRD）在典型的结构材料上生长微型薄膜有源传感器阵列，用于先进的结构健康监测应用。适当的缓冲界面，以确保持久的铁电薄膜的结构材料和连贯的外延生长的粘附将被开发。高性能、环境友好的铁电复合材料将得到发展。建模和分析将用于开发缓冲接口，纳米加工处理方法，和兰姆/瑞利波相控阵算法，这些新设备的结构健康监测应用。该提案的高度跨学科性质由一个传感器小组负责，该小组的成员来自材料科学，电气工程，机械工程和物理学，跨越四所大学（路易斯安那州立大学、宾夕法尼亚州立大学、南卡罗来纳州大学、德克萨斯大学圣安东尼奥分校），其中一所为西班牙裔服务机构（HSI）：该项目将采用分析建模，数值模拟和实验验证。它将建立在各个调查人员获得的初步结果的基础上。除技术活动外，该项目还将开展重要的传感器教育和推广活动。这是一个EPSCoR研究项目，得到传感器招标NSF 05-625的支持。
