Fish possess high sensitivity to acoustic, vibrational, and hydrodynamic stimuli through unique sensing cells, providing unparalleled paradigms for developing underwater detection methods. However, artificial perception devices face challenges in replicating comparable sensitivity and multi-dimensional integration of fish in function and scale. Here, we propose a biomimetic optical fiber neuromast (BOFN) by leveraging synergistic optical-mechanical interactions for multifunctional underwater detection and communication. A heterogeneous integration technology for BOFN is developed based on sequential femtosecond laser direct writing with deposition, resulting in both compact size and reliable stability. Benefiting from its biomimetic design, BOFN demonstrates performance benchmarks in acoustic sensitivity of 172.24 V/kPa and marine turbulence sensitivity of 8560.72 nm/(m/s). A prototype system integrated into a motorized fish shows versatile acoustic sensing, target imaging, and underwater communication capabilities. Our work opens avenues for deploying all-optical bionic sensing cells in underwater environments, with promising applications in marine resource exploration and ecosystem protection.
鱼类通过独特的传感细胞对声学、振动和流体动力刺激具有高度敏感性，为开发水下探测方法提供了无与伦比的范例。然而，人工感知设备在复制鱼类在功能和规模上可比的灵敏度和多维集成方面面临挑战。在此，我们通过利用协同光机械相互作用提出一种仿生光纤神经丘（BOFN），用于多功能水下探测和通信。基于飞秒激光直接写入与沉积的顺序开发了一种用于BOFN的异质集成技术，从而实现了紧凑的尺寸和可靠的稳定性。受益于其仿生设计，BOFN在声学灵敏度方面表现出172.24 V/kPa的基准性能，在海洋湍流灵敏度方面表现出8560.72 nm/(m/s)的基准性能。集成到机动鱼中的原型系统展示了多功能声学传感、目标成像和水下通信能力。我们的工作为在水下环境中部署全光仿生传感细胞开辟了道路，在海洋资源勘探和生态系统保护方面具有广阔的应用前景。
