Biomimetics

I am taking a break from studying geometry and have moved on like a crow to a new shiny thing that has caught my eye---biomimetics. Biomimetics is where engineering meets biology, it is basically stealing natures evolutionary tricks to create revolutionary applications. An example would be science trying to copy the feet of a lizard or gecko in order to make vehicles that can scale walls etc. It is almost like looking through God's notes and stealing some ideas. Da Vinci employed this kind of thought quite often in his work and notes. A current example is the development of a material (inspired by a sea slug) that is hard and then soft when water is added. This material could be better used as a way to add an electrode tho the brain that would last longer than current electrodes which destroy the surrounding soft brain tissue because they are hard.
