A Wave Energy Converter (WEC) harvests clean and green energy from ocean waves. Traditionally, they use multiple rigid bodies, but there is significant cost potential from use of flexible membranes (mWEC) as the main interaction with the waves. Survivability and reliability of these highly deformable membrane structures is a key concern. An mWEC operating underwater experiences multiple modes of deformations (tension, compression, bending/twisting; in- and out-of-plane deformations) during its service life. Hence, ensuring reliability of membrane structures through constant health monitoring in damage-prone areas using stretchable sensors is an ideal choice. However, the integration of stretchable sensors in mWEC face several challenges, i) design of multi-modal sensor networks that can simultaneously capture in-and out-of-plane deformations, ii) arrangements of sensor electronics in submerged conditions and iii) experimental validation of sensor' responses mimicking sub-sea conditions using a recently purchased multi-axial test rig. The sensors will also be applied to monitoring wind turbine blades. We will address the aforementioned scientific challenges in this project.

波浪能转换器（WEC）从海浪中收集清洁和绿色能源。传统上，它们使用多个刚体，但使用柔性膜（mWEC）作为与波浪的主要相互作用存在显著的成本潜力。这些高度可变形的膜结构的生存性和可靠性是一个关键问题。水下运行的mWEC在其使用寿命期间经历多种变形模式（拉伸、压缩、弯曲/扭转;平面内和平面外变形）。因此，通过使用可拉伸传感器在易损坏区域进行持续健康监测来确保膜结构的可靠性是一个理想的选择。然而，可拉伸传感器在mWEC中的集成面临几个挑战，i）可以同时捕获平面内和平面外变形的多模态传感器网络的设计，ii）传感器电子器件在浸没条件下的布置，以及iii）使用最近购买的多轴测试装置模拟海底条件的传感器响应的实验验证。该传感器还将用于监测风力涡轮机叶片。我们将在本项目中解决上述科学挑战。
