Abstract：
Marine animals equipped with sensors provide vital information for understanding their ecophysiology and collect oceanographic data on climate change and for resource management. Existing methods for attaching sensors to marine animals mostly rely on invasive physical anchors, suction cups, and rigid glues. These methods can suffer from limitations, particularly for adhering to soft fragile marine species such as squid and jellyfish, including slow complex operations, unreliable fixation, tissue trauma, and behavior changes of the animals. However, soft fragile marine species constitute a significant portion of ocean biomass (>38.3 teragrams of carbon) and global commercial fisheries. Here we introduce a soft hydrogel-based bioadhesive interface for marine sensors that can provide rapid (time <22 s), robust (interfacial toughness >160 J m-2), and non-invasive adhesion on various marine animals. Reliable and rapid adhesion enables large-scale, multi-animal sensor deployments to study biomechanics, collective behaviors, interspecific interactions, and concurrent multi-species activity. These findings provide a promising method to expand a burgeoning research field of marine bio-sensing from large marine mammals and fishes to small, soft, and fragile marine animals.
摘要：
配备传感器的海洋动物为了解其生态生理学提供了重要信息，并收集了有关气候变化和资源管理的海洋学数据。现有的将传感器附着到海洋动物上的方法大多依赖于侵入性物理锚，吸盘,和刚性胶水。这些方法可能会受到限制，特别是粘附到软脆弱的海洋物种，如鱿鱼和水母，包括缓慢的复杂操作，不可靠的固定，组织创伤,和动物的行为变化。然而,软脆弱的海洋物种构成了海洋生物量(>38.3万亿碳)和全球商业渔业的重要部分。在这里，我们介绍了一种用于海洋传感器的基于软水凝胶的生物粘附界面，该界面可以提供快速（时间<22s），坚固（界面韧性>160Jm-2），以及对各种海洋动物的非侵入性粘附。可靠和快速的粘附使大规模，多动物传感器部署以研究生物力学，集体行为,种间相互作用，和并发的多物种活动。这些发现提供了一种有希望的方法，将海洋生物传感的新兴研究领域从大型海洋哺乳动物和鱼类扩展到小型，软,脆弱的海洋动物
