Inventions based on the examples that we find around us in nature are commonplace. Now a suit inspired by hedgehogs has been designed. The creator has drawn upon the hedgehog’s spines and ability to roll into a tight ball, both of which protect hedgehogs from predation. I'm not sure humans will ever take to wearing these suits on a daily basis as the wearer would be somewhat more cumbersome than hedgehogs, which can move very quickly when needed.
These airbags provide a huge ball of cushioning to protect the vital organs and bones - particularly around the head and upper body. The hedgehog was used as inspiration because of the animal’s ability to role into the foetal position to protect vulnerable parts of the body.
