Developing multifunctional flying perceptibility, by mimicking the biological system, is meaningful for aircrafts to adapt to the complicated and ambiguous flow environment. In this work, we show that the comprehensive capabilities (skin, synapse, immune system, and brain) of flying creatures can serve as bio-inspirations to develop an intelligent flexible sensing (iFlexSense) skin with similar components, i.e., skin-like mechanosensing, neuron-like data transmission, immune system-like impact monitoring and brain-like artificial intelligence. The iFlexSence skin brings substantial improvements to the aircrafts by the multifunctionalities including airflow perception, state awareness and self-diagnosis of complex surfaces, validated by the wind tunnel tests mounted on a NACA 0012 airfoil, in which it accurately measures the surface pressure, temperature, wall shear stress and flutter, locates the sudden impacts and correctly predicts the occurrence of separation and stall. It shows great potential for future wind tunnel tests and to extend the capabilities of unmanned air vehicles and underwater vehicles.

通过模仿生物系统开发多功能飞行感知能力，对于飞机适应复杂、模糊的流动环境具有重要意义。在这项工作中，我们展示了飞行生物的综合能力（皮肤、突触、免疫系统和大脑）可以作为生物灵感来开发具有相似组件的智能柔性传感（iFlexSense）皮肤，即类皮肤机械传感、类似神经元的数据传输、类似免疫系统的影响监测和类似大脑的人工智能。iFlexSence 皮肤通过多种功能为飞机带来了实质性的改进，包括气流感知、状态感知和复杂表面的自我诊断，并通过安装在 NACA 0012 翼型上的风洞测试进行验证，其中它准确地测量了表面压力，温度、壁面剪应力和颤振，定位突然撞击并正确预测分离和失速的发生。它显示了未来风洞测试和扩展无人机和水下航行器能力的巨大潜力。
