Aquatic systems are highly interconnected, which allow fish to traverse long distances, to dive through a water column, and, for some species, to move between fresh and saltwater environments. There is critical and urgent need for long-life unremitting fish monitoring technologies that can help with understanding fish behavior, selecting offshore wind farm sites, operating hydroelectric power plants, and assessing environmental impacts of marine hydrokinetic energy systems. The total market value of global telemetry including fish telemetry tags is estimated to reach $243 billion by 2020. Current fish telemetry tags are constrained by the limited lifetime of batteries, and periodic battery replacements are expensive and harmful to the fish. Another challenge is how to attach these tags to a fish with minimum impact on its normal life. Implanting a tag inside a fish body constitutes a complicated surgery process with the risk of impeding the fish life, and the mechanical clamping to the fin may negatively affect the fish motions. Therefore, this proposal aims at investigating a self-powered strategy and a bio- inspired attachment method for fish telemetry tags through energy harvesting from the surrounding fluid and fish maneuvering.The goals of this GOALI project are to design and validate a novel bio-inspired attachment with a minimal influence on fish life and mobility and a bio-inspired broadband energy harvester to achieve a self-powered fish telemetry tag. The proposed bio-inspired fish tag consists of a bio-inspired bi-stable energy harvester, a bio-inspired sucking disc, an acoustic transmitter, and an integrated circuit board that contains both the transmission circuit, sensors, and the energy-harvesting management circuit. Particularly, the principle behind the Venus flytrap will be fully understood to investigate the snap-through dynamics of the proposed bi-stable galloping piezoelectric harvester subjected to the combined excitations from fish maneuver and fluid flow. The remora-shark "symbiotic relationship" will be studied and used to guide the design of the bio-inspired sucking pad with stiff metal-based teeny spikes (in mimic the lamellar spinules) to attach the harvester on the fish. The specific work scope includes (1) a bio-inspired design of an attachment mechanism and a self-power sensing and communication system, (2) modeling of the fluid-structure-piezoelectric interaction, (3) the bio-inspired dynamics of the bi-stable piezoelectric energy harvester under complex excitations, and (4) experimental validation on robotic fish, live fish, and on-site demonstrations to investigate the performance and the influence of harvester on the fish life and mobility. The research is integrated with an educational and outreach plan, including course development, undergraduate research, K-12 students and teachers, and opportunities for minorities and women. The active collaboration between the two universities and industry will guide fundamental research to solve a critical industry need and enable wide dissemination and accelerated implementation of developed knowledge with immediate industry impacts.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.

水生系统是高度相互关联的，这使得鱼类能够长距离穿越，潜入水柱，并且对于某些物种来说，可以在淡水和咸水环境之间移动。迫切需要长期不间断的鱼类监测技术，以帮助了解鱼类行为、选择海上风电场地点、运营水力发电厂以及评估海洋流体动力能源系统的环境影响。到2020年，包括鱼类遥测标签在内的全球遥测总市场价值预计将达到2430亿美元。当前的鱼类遥测标签受到电池寿命有限的限制，定期更换电池成本高昂且对鱼类有害。另一个挑战是如何将这些标签贴在鱼身上，同时对其正常生活的影响最小。在鱼体内植入标签是一个复杂的手术过程，有阻碍鱼生命的风险，并且对鳍的机械夹紧可能会对鱼的运动产生负面影响。因此，本提案旨在研究一种自供电策略和一种生物启发的鱼类遥测标签附着方法，通过从周围流体和鱼类操纵中收集能量。该 GOALI 项目的目标是设计和验证一种新型生物启发的方法。对鱼类生命和活动性影响最小的附件和仿生宽带能量采集器，以实现自供电鱼类遥测标签。拟议的仿生鱼标签由仿生双稳态能量采集器、仿生吸盘、声学发射器和包含传输电路、传感器和能量采集管理的集成电路板组成电路。 特别是，我们将充分理解捕蝇草背后的原理，以研究所提出的双稳态驰骋压电采集器在鱼类机动和流体流动的联合激励下的突弹动力学。鲳鱼和鲨鱼的“共生关系”将被研究并用于指导仿生吸盘的设计，吸盘带有坚硬的金属基小尖刺（模仿层状小刺），以将收割机固定在鱼身上。具体工作范围包括（1）附着机构和自供电传感和通信系统的仿生设计，（2）流体-结构-压电相互作用的建模，（3）仿生动力学复杂激励下的双稳态压电能量采集器；（4）对机器鱼、活鱼进行实验验证并进行现场演示，以研究采集器的性能以及对鱼的生命和活动性的影响。该研究与教育和推广计划相结合，包括课程开发、本科生研究、K-12 学生和教师以及少数族裔和女性的机会。两所大学和行业之间的积极合作将指导基础研究，以解决关键的行业需求，并促进广泛传播和加速实施具有直接行业影响的已开发知识。该奖项反映了 NSF 的法定使命，并通过使用评估结果被认为值得支持。基金会的智力价值和更广泛的影响审查标准。
