The broader impact/commercial potential of this Small Business Technology Transfer (STTR) project seeks to provide an integrated monitoring solution for wind turbine blades. Continuous and reliable monitoring within the blade has been a challenge, primarily due to the lack of reliable energy for the wireless sensor (e.g., batteries need to be replaced and can be expensive and logistically difficult to replace inside the blade and power lines inside the blade are hard to install and require frequent maintenance). The proposed solution seeks to overcome current technical challenges by providing a long-lasting, maintenance-free, self-powered, integrated solution for wind turbine blade monitoring and analytics. If successfully commercialized, the solution can be deployed for autonomous sensing and smart maintenance scheduling based on big data analysis. This project may contribute to significantly and permanently reducing existing blade monitoring costs, decreasing downtime for manual monitoring and battery changes and reducing catastrophic failures with better monitoring information. By reducing the operational costs, the solution may make large-scale wind energy more competitive, reducing the world’s dependence on environmentally-harmful sources of energy. In addition, the technology may reduce the risk of injury to humans as compared to current operational processes, making wind energy safer to operate. This STTR Phase I project proposes to develop an integrated, self-powering sensor node for wind turbine blade monitoring by overcoming the following technical hurdles: lack of reliable energy for the sensor/transmitter system deep inside the blade, logistical challenges to replacing batteries inside the blade for a large number of sensors at different intervals, and difficulites with long wire-runs inside the blade as those are hard to install and require frequent maintenance. To handle these technical hurdles, this project aims to prototype an integrated, self-powered, wireless sensor node and perform field tests. This project plans to: (1) develop a mechanism for the harvester module that reliably produces electrical voltage and power regardless of the blade rotational speed, (2) develop a power management circuit with autonomous sleep/wakeup and without impedance tracking to increase charging efficiency, and (3) perform indoor and in-field test for verification of power harvesting and data transmission performance. This technolology seeks to address the fundamental weaknesses of vibration energy harvesters while integrating various components (e.g., energy harvester, sensor, transmitter, receiver, and analytics software) for an optimized solution.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.

这个小型企业技术转移（STTR）项目的更广泛的影响/商业潜力旨在为风力涡轮机叶片提供集成的监测解决方案。刀片中的连续可靠的监视是一个挑战，这主要是由于无线传感器缺乏可靠的能量（例如，需要更换电池，并且在刀片内部的刀片内部和电源线内部很难更换刀片，并且在刀片内部很难更换，并且很难安装刀片，并且需要安装频率维护）。拟议的解决方案旨在通过为风力涡轮机叶片监测和分析提供持久，无维护，自供电，集成的解决方案来克服当前的技术挑战。如果成功商业化，则可以根据大数据分析来部署该解决方案以进行自主灵敏度和智能维护计划。该项目可能会大大降低现有的刀片监测成本，减少手动监控和电池更换的停机时间，并通过更好的监视信息减少灾难性故障。通过降低运营成本，该解决方案可能会使大规模的风能更具竞争力，从而减少了世界对环保能源的依赖。此外，与当前的运营过程相比，该技术可能会降低人类受伤的风险，从而使风能更安全。 This STTR Phase I project proposals to develop an integrated, self-powering sensor node for wind turbine blade monitoring by overcoming the following technical hurdles: lack of reliable energy for the sensor/transmitter system deep inside the blade, logistical challenges to replace batteries inside the blade for a large number of sensors at different intervals, and difficulties with long wire-runs inside the blade as those are hard to install and require frequently maintenance.为了应对这些技术障碍，该项目旨在原型制作集成，自我的无线传感器节点并执行现场测试。该项目计划：（1）为收割机模块开发一种机制，该机制可靠地产生电压和电源，而不论刀片旋转速度如何，（2）开发具有自主睡眠/唤醒的电源管理电路，并且没有阻碍跟踪以提高充电效率，并且（3）执行室内和现场测试以验证电力收获和数据传输性能的验证。该技术旨在解决振动能量收获者的根本弱点，同时将各种组件（例如能源收割机，传感器，发射器，接收器和分析软件）整合到优化的解决方案中。该奖项反映了NSF的法定任务，并认为通过基金会的知识优点和广泛的crigitia criperia criperia criperia criperia criperia criperia criperia criperia criperia criperia rection criptiation recsiped this奖。
