本文介绍了一种用于动物遥测标签的新型仿生双稳压电能量采集器的概念设计、初步实验验证和性能评价。首先介绍了该装置的总体概念设计，包括仿生附着体和双稳态压电式能量采集器，并给出了一个海水鱼类跟踪的具体应用实例。自力式遥测标签可以外部安装在鱼(背鳍)上，以监测鱼的栖息地、种群和水下环境。受捕蝇器快速形状转变的启发，开发了一种双稳态压电能量收集器，以从鱼类的机动和周围的流体中收集能量，以实现可持续的电力供应。通过测力-位移曲线和双势垒来表征收割机的双稳态。在双稳态压电能量采集器的自由端集成了钝体，以增强结构-流体的相互作用，从而实现大幅度的突跃振动和更高的电压输出。在仿生双稳态压电式能量采集器的水箱中，利用伺服电机系统模拟鱼在不同条件下的摆动运动，对其发电性能进行了实验室控制实验。初步的水下实验结果表明，所提出的仿生双稳态压电能量采集器能够有效地将鱼的摆动转化为电能。在电容器充电实验中，该装置在30oat 1.5 GHz的峰峰摆角下收集了超过130mJ的17.25mJ的能量给S。
This paper presents the conceptual design, preliminary experimental validation, and performance evaluation of a novel bio-inspired bi-stable piezoelectric energy harvester for self-powered animal telemetry tags. The overall conceptual design, which includes a bio-inspired attachment and a bi-stable piezoelectric energy harvester, is introduced firstly with a specific application example of marine fish tracking. The self-powered telemetry tag can be externally deployed on fish (dorsal fin) to monitor fish habitats, population, and underwater environment. Inspired by the Venus flytrap's rapid shape transition, a bi-stable piezoelectric energy harvester is developed to scavenge energy from fish maneuvering and the surrounding fluid flow for a sustainable power supply. The bistability of the harvester is characterized by the measured force-displacement curve and double potential wells. A bluff body is integrated to the free end of the bistable piezoelectric energy harvester to enhance the structure-fluid interaction for the large-amplitude snap-through vibrations and higher voltage output. Controlled laboratory experiments are conducted in a water tank on the bio-inspired bi-stable piezoelectric energy harvester using a servo motor system to simulate fish swing motion at various conditions to evaluate the power generation performance. The preliminary underwater experimental results demonstrated that the proposed bio-inspired bi-stable piezoelectric energy harvester could effectively convert fish swing motions into electricity. The device collected 17.25 mJ of energy over 130 s under a peak-to-peak swing angle of 30oat 1.5 Hz in the capacitor charging experiments.
