Lightweight Construction Inspired by Nature

Over millions of years, many organisms have developed highly optimized structures. Diatoms—microscopic algae with delicate silicate shells—are a particularly striking example. Despite requiring only minimal material, their structures exhibit remarkable stability.

Researchers at the Alfred Wegener Institute (AWI) analyze natural lightweight construction systems and transfer their design principles to technical applications. This methodology led to the development of the ELiSE (Evolutionary Light Structure Engineering) method. It combines biological analyses with mechanical testing and computer-aided development processes. 

The resulting principles form the basis for the design of technical structures that require significantly less material while maintaining the same level of stability. This approach reduces resource consumption, energy demand, and structural weight.

The method is already being applied in industrial projects, for example, in the development of components for automobiles, household appliances, and offshore wind turbines. The underlying software helps engineers systematically translate natural design principles into technical applications.

What began as basic research on microscopic marine organisms is now contributing to the development of more efficient and sustainable technical structures.
