Abstract

With increasing attention on the world's oceans, a significant amount of research has been focused on the sensing of marine-related parameters in recent years. In this paper, a bioinspired flow sensor with corrosion resistance, anti-interference capability, a portable design structure, easy integration, and directional sensing ability is presented to realize flow speed sensing in open water. The sensor is realized by a flexible artificial cupula that seals one side of an optical fiber acting as an artificial kinocilium. Below the artificial kinocilium, an encapsulated s-tapered optical fiber mimics the fish neuromast sensory mechanism and is supported by a 3D-printed structure that acts as the artificial supporting cell. To characterize the sensor, the optical transmission spectra of the sensory fiber under a set of water flow velocities and four orthogonal directions were monitored. The sensor's peak intensity responses were found to demonstrate flow sensing ability for velocity and direction, proving that this biomimetic portable sensing structure is a promising candidate for flow sensing in marine environments.

基于非对称光纤传感结构的仿生物正交流量传感器，用于海洋传感。

随着人们对世界海洋的关注与日俱增，近年来大量研究都集中在海洋相关参数的传感上。本文介绍了一种生物启发式流量传感器，它具有耐腐蚀、抗干扰能力强、设计结构便携、易于集成和定向传感能力强等特点，可实现开放水域的流速传感。该传感器由一个柔性人工冲天管实现，它将光纤的一侧密封起来，充当人工动丝。在人造纤毛器下方，封装的 s 锥形光纤模仿了鱼类神经乳突的传感机制，并由作为人造支撑细胞的 3D 打印结构支撑。为了确定传感器的特性，我们监测了传感光纤在一组水流速度和四个正交方向下的光传输光谱。结果发现，传感器的峰值强度响应显示了对流速和方向的流量感应能力，证明这种仿生物便携式感应结构是海洋环境中流量感应的理想候选结构。

期刊介绍： Bioinspiration & Biomimetics publishes research involving the study and distillation of principles and functions found in biological systems that have been developed through evolution, and application of this knowledge to produce novel and exciting basic technologies and new approaches to solving scientific problems. It provides a forum for interdisciplinary research which acts as a pipeline, facilitating the two-way flow of ideas and understanding between the extensive bodies of knowledge of the different disciplines. It has two principal aims: to draw on biology to enrich engineering and to draw from engineering to enrich biology. The journal aims to include input from across all intersecting areas of both fields. In biology, this would include work in all fields from physiology to ecology, with either zoological or botanical focus. In engineering, this would include both design and practical application of biomimetic or bioinspired devices and systems. Typical areas of interest include: Systems, designs and structure Communication and navigation Cooperative behaviour Self-organizing biological systems Self-healing and self-assembly Aerial locomotion and aerospace applications of biomimetics Biomorphic surface and subsurface systems Marine dynamics: swimming and underwater dynamics Applications of novel materials Biomechanics; including movement, locomotion, fluidics Cellular behaviour Sensors and senses Biomimetic or bioinformed approaches to geological exploration.
