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）从海浪中收获清洁和绿色的能量。传统上，它们使用多个刚体，但是使用柔性膜（MWEC）作为与波浪的主要相互作用，具有巨大的成本潜力。这些高度变形的膜结构的生存能力和可靠性是关键问题。 MWEC操作的水下经历了多种变形模式（张力，压缩，弯曲/扭曲；平面外和非平面变形）在其使用寿命期间。因此，通过使用可伸缩传感器在容易受损的区域内持续的健康监测来确保膜结构的可靠性是理想的选择。但是，MWEC中可拉伸传感器的集成面临几个挑战，i）设计多模式传感器网络，可以同时捕获平面外变形的多模式传感器网络；传感器还将应用于监测风力涡轮机叶片。我们将解决该项目中上述科学挑战。
