This Small Business Technology Transfer (STTR) Phase I project will examine the use of a novel, ultrasonic materials consolidation technology as a means to embed Bragg intracore grating, fiber optic strain sensors as part of a real-time asset monitoring information system. The embedding process for strain sensors using ultrasonic consolidation will be the focus of an extensive analysis of the nanoscale materials processing, structure and properties relationship. For example, the bonding of the ductile, metallic embedding environment with the ceramic devices and the bonding of the devices with a bridge, building, or dam will likely require the development of nanoscale engineering of the metal/ceramic or metal/metal interfaces. The ultimate focus will be on combining the information technology of optical fiber structural analysis with the nanoscale engineering of ultra-sonic consolidation to produce rugged, embedded, real time measurement of strain.The convergence of these technologies could produce unparalleled capability for retrofitting structures to allow visibility into continuity, integrity, stability and damage assessment using real time transmission of information. Structural health monitoring is a critical need not only to utilize prognostic analysis on a rapidly or gradually failing structure, but to provide tactical situation analysis from a site that may have experienced a significant trauma event. For example, structural asset visibility would allow large complexes, such as a dam, to anticipate future failure events as trend-based strain data would highlight potential system irregularities. In addition to this, the proposed solution would also provide first responders with that same real-time structure health data had there been some form of singular attack or natural disaster. In both cases the embedded sensor technology would be providing value to the site on both an economic and security basis.

这个小型企业技术转移（STTR）I期项目将研究使用一种新型超声材料合并技术作为嵌入Bragg bragge胶粒光纤，光纤应变传感器的一种手段，作为实时资产监控信息系统的一部分。 使用超声合并的应变传感器的嵌入过程将是对纳米级材料处理，结构和性质关系的广泛分析的重点。例如，延性，金属嵌入环境与陶瓷设备的键合以及设备与桥梁，建筑物或大坝的键合可能需要开发金属/陶瓷或金属/金属界面的纳米级工程。最终的重点将是将光纤结构分析的信息技术与超声巩固的纳米级工程相结合，以产生崎,、嵌入式的，实时测量应变的实时测量。这些技术的融合可以产生无与伦比的能力，以使改进结构能够使用连续性，稳定性，实时评估，以实现稳定性，实时评估信息，以实现稳定性。 结构性健康监测不仅是在结构快速或逐渐失败的结构上利用预后分析的至关重要的必要性，而且还需要从可能经历过重大创伤事件的现场提供战术状况分析。例如，结构资产的可见性将使大型复合物（例如大坝）预测未来的故障事件，因为基于趋势的应变数据将突出潜在的系统不规则性。除此之外，如果存在某种形式的奇异攻击或自然灾害，则提出的解决方案还将为急救人员提供相同的实时结构数据。在这两种情况下，嵌入式传感器技术都将以经济和安全为基础为该站点提供价值。
