The ultimate goal of the proposed research project is the development of a new class of self-sensing materials, which have the ability to mange data flow from the sizable number of embedded sensors by use of local processing techniques. To be addressed first will be the fabrication issues to include the electronic, sensing and connection elements within a fiber-reinforced composite. Initially the work will be directed to demonstrating a proof-of-concept self-sensing material, capable of monitoring temperature flow patterns with the composite. Miniaturized MEMS based sensors capable of measuring such quantities such as acceleration, rotation and acoustic emission will be developed Hierarchical algorithms will be developed to manage the data expected from the sensor network. The 5-year research will be carried out by a multidisciplinary team made of Principal Investigator who is a civil/materials engineer and three Co-Principal Investigators who span mechanical, physics and applied mathematics. On-going research by the PIs in the area of fabrication of composites with tailored electromagnetic properties will provide a foundation for the proposed research. The proposed research includes collaboration with Lucent Technologies, which would provide substantial expertise and capability in MEMS fabrication and facilitate the technical transfer of the research outcome. The project includes three specific outreach programs to engage high school and undergraduate students, and a plan to establish a Summer Research Program and summer internship for underrepresented students.This is an NSF 03-512 project.___________________

拟议研究项目的最终目标是开发一种新型的自传感材料，这种材料能够通过使用本地处理技术来管理来自大量嵌入式传感器的数据流。首先要解决的是制造问题，包括纤维增强复合材料中的电子、传感和连接元件。最初的工作将是展示一种概念验证的自传感材料，能够监测复合材料的温度流动模式。将开发能够测量加速度、旋转和声发射等量的小型化MEMS传感器，并开发分层算法来管理传感器网络的预期数据。这项为期5年的研究将由一个多学科团队进行，该团队由首席研究员（土木/材料工程师）和三名联合首席研究员（机械、物理和应用数学）组成。pi正在进行的具有定制电磁特性的复合材料制造领域的研究将为拟议的研究提供基础。拟议的研究包括与朗讯科技合作，这将提供大量的MEMS制造专业知识和能力，并促进研究成果的技术转移。该项目包括针对高中生和大学生的三个具体拓展项目，以及为代表性不足的学生建立暑期研究项目和暑期实习的计划。这是一个NSF 03-512项目。___________________
