The broader impact/commercial potential of this I-Corps project on the new dynamic distributed fiber optic strain technology is that it could be applied within a field that requires or could benefit from a high density of data for strain or temperature detection. Infrastructure is a large part of a nation's assets and efficient management of these assets is vital to society. The lack of rich data on structural performance limits our understanding of infrastructure behavior. The new technology can provide a single distributed monitoring system for large infrastructure projects in civil engineering, such as bridges, tunnels, foundations, dams, levees, etc.; or in the oil and gas industry such as for methane hydrate excavation, deep wells, surface or buried pipelines, and shale gas excavation monitoring. Through the use of monitoring systems centered on this technology, clients would be provided quality control data to observe and validate the construction of their assets and their long-term performance, potentially over the entire asset lifespan. The produced monitoring data can be presented and shared within a network data map that can be adopted as part of the 'smart city' approach for both hazard prevention or future city management.This I-Corps project explores commercial opportunities for the new distributed fiber optic sensor system technology that reduces the reading time and provides the dynamic detection capability for strain or temperature sensing. The newly developed system provides very high density of data (every 2cm) over very long distance (10-50km), giving equivalent of thousands of conventional 'strain gauge', 'thermo-couple' or 'accelerometer' instruments through the use of a single low-cost fiber optic cable. Its dynamic performance opens a window of detection linear wave vibration along the fiber cable and detects the response of the infrastructural under external load or even seismic event. The I-Corps team will interview potential clients, stakeholders, and key business adopters to better understand the monitoring needs and current areas for improvement within the marketplace. This exercise will allow the team to determine the potential commercial viability of the technology, as well as help identify potential areas for further research as well as other markets for deployment that are not currently using distributed fiber optic sensing.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该I-Corps项目对新的动态分布式光纤应变技术的更广泛的影响/商业潜力是，它可以应用于需要或可能从高密度的数据中受益于应变或温度检测的领域。基础设施是一个国家资产的很大一部分，对这些资产的有效管理对社会至关重要。缺乏关于结构性绩效的丰富数据限制了我们对基础设施行为的理解。 这项新技术可以为土木工程中的大型基础设施项目提供单个分布式监控系统，例如桥梁，隧道，基金会，大坝，堤防等；或在石油和天然气行业中，例如用于甲烷水合物发掘，深井，地面或掩埋的管道以及页岩气挖出监测。通过使用以这项技术为中心的监视系统，将提供客户的质量控制数据，以观察和验证其资产的构建及其长期绩效，这可能在整个资产寿命中。可以在网络数据图中呈现和共享生产的监视数据，该数据可以作为预防危险或未来城市管理的“智能城市”方法的一部分。该I-Corps项目探索了新的分布式光纤传感器系统技术的商业机会，以减少阅读时间，并为应变或温度传感提供动态检测能力。新开发的系统在很长的距离内（10-50 km）提供了非常高的数据密度（每2厘米），相当于数千种常规的“应变量表”，“热电组”或“加速度计”仪器，通过使用单个低调的光纤电缆。它的动态性能打开了沿光纤电缆的检测线性波振动窗口，并在外部负载甚至地震事件下检测基础结构的响应。 I-Corps团队将面试潜在客户，利益相关者和主要业务采用者，以更好地了解市场内改善的监视需求和当前领域。这项练习将使团队能够确定技术的潜在商业生存能力，并有助于确定进一步研究的潜在领域以及其他目前尚未使用分布式光纤传感的部署市场。该奖项反映了NSF的法定任务，并被认为是通过基金会的智力和宽广的影响来评估的支持，并被认为是值得的。
