The Knowledge Transfer Network is building a new UK network, showcasing the benefits of new product development design teams inspired by nature. This event showcase how biomimicry and nature inspired solutions are being used in established innovation processes from a section of innovative companies and it’s an opportunity to learn about how to implement and benefit from Nature Inspired Solutions.

What are Nature Inspired Solutions?

In the past Biomimicry or Biomimetics started from simple imitation of natural organisms. Over time, it has evolved through integration and combination with modern science and engineering to help us discover new materials, ways of combining nano/microstructures, applications, and alternative ways of production and process design thinking leading to nature inspired or bio inspired engineering. Rather than imitating the whole plant, animal or biological process, nature-inspired solutions aim to uncover the underlying mechanisms and apply them in the design of new products, processes or systems in a structured way.

This Nature Inspired Solutions Special Interest Group (NIS SIG) aims to convene and grow the nature inspired solution community and accelerate innovation through cross-sector collaborations.

A helicoidal wall structure is much stronger than having all the cellulose oriented in one parallel sheet. The latter would tend to split axially and fail to resist shear forces. A helicoidal ply combines a balance of strength in all directions with flexibility. https://doi.org/10.1007/BF00396750 0.5 µm https://doi.org/10.1016/j.actbio.2015.04.039 https://doi.org/10.1038/ncomms3634
