Engineering

By taking nature as a role model, scientists develop ideas and products that can be specifically adapted to environmental conditions. This method allows us to specifically influence the behavior of mechanical structures: reducing the weight, increasing the stiffness or actively controlling the shape. Using the right design methodology in early stages of the development process makes it possible to provide great progress in terms of product quality.
