Bluebird-inspired material could boost battery life

Bluebird-inspired material could boost battery life

the brilliant blue of the bird’s wings isn’t the result of colour pigmentation. Instead, it’s due to a network of channels with a diameter of a few hundred nanometres, traversing the feathers.

This network structure inspired researchers at ETH Zurich to replicate this material in the lab. They have now developed a synthetic material that exhibits the same structural design of the bluebird’s feathers — with the potential to deliver practical use cases, such as improved battery life…
