March 5, 2026 – Scientists in China have developed a new material design inspired by the structure of sea urchins. These organisms have a skeleton that adapts efficiently to water flow. By mimicking this principle, researchers created a material that can harness movement and force from flowing environments. This could be applied in energy generation, sensors, and marine technologies. The design combines strength with flexibility, allowing it to withstand changing conditions. It also reduces energy loss by adjusting to flow direction and speed. The study demonstrates how biological structures can inform technological innovation.

The study was published in Nature in late February under the title ‘Echinoderm stereom gradient structures enable mechanoelectrical perception’. It is online>
