摘要
We propose and describe an anemovane that can detect wind speed in all directions owing to its sea urchin-like shape. In this design, cantilevers project from the sphere, imitating sea-urchin prickles. When wind hits the cantilevers, the pressure sends a voltage signal through the piezoelectric unimorph bender. The velocity of the wind can then be calculated from this voltage signal. This research describes the theoretical analysis of the piezoelectric unimorph bender and the multi-physics analysis performed by combining the fluid, the solid structure, and the piezoelectric material, and the verification of the optimal design.
