Conventional approaches to studying fish kinematics pose a great challenge for the real-time monitoring of fish motion kinematics. Here, a multifunctional fish-wearable data snooping platform (FDSP) for studying fish kinematics is demonstrated based on an air sac triboelectric nanogenerator (AS-TENG) with antibacterial coating. The AS-TENG not only can harvest energy from fish swimming but also serves as the self-powered sensory module to monitor the swimming behavior of the fish. The peak output power generated from each swing of the fishtail can reach 0.74 mW, while its output voltage can reflect the real-time behavior of the fishtail. The antibacterial coating on the FDSP can improve its biocompatibility and the elastic texture of the FDSP allows it to be tightly attached to fish. The wireless communication system is designed to transmit the sensory data to a cell phone, where the detailed parameters of fish motion can be obtained, including swing angle, swing frequency, and even the typical swing gestures. This FDSP has broad application prospects in underwater self-powered sensors, wearable tracking devices, and soft robots.
传统的鱼类运动学研究方法对鱼类运动学的实时监测提出了巨大挑战。在这里，展示了一种基于带有抗菌涂层的气袋摩擦纳米发电机 (AS-TENG) 的多功能鱼类可穿戴数据窥探平台 (FDSP)，用于研究鱼类运动学。该 AS-TENG 不仅可以从鱼类游动中收集能量，还可以作为自供电的传感模块来监测鱼类的游动行为。鱼尾每次摆动产生的峰值输出功率可达 0.74 mW，而其输出电压可以反映鱼尾的实时行为。FDSP 上的抗菌涂层可以提高其生物相容性，FDSP 的弹性质地使其可以紧密贴合鱼类。设计了无线通信系统将传感数据传输到手机，在手机上可以获得鱼类运动的详细参数，包括摆动角度、摆动频率，甚至是典型的摆动姿势。这种 FDSP 在水下自供电传感器、可穿戴跟踪设备和软体机器人方面具有广阔的应用前景。
