5. 4Biomimicry Preface “Nature creates materials of an intricacy and functionality that we can only dream of. The inner shell of Abalone is twice as tough as our high tech ceramics. Spider silk, ounce for ounce, is five time stronger than steel. Mussel Adhesive works underwater and sticks to anything, even without a primer. Bone, wood, skin, tusks, antlers, and heart muscle - miracle materials all - are made to live out their useful life and then to fade back, to be reabsorbed by another kind of life through the grand cycle of death and renewal.” http://academic.evergreen.edu/j/jirtas12/Biomimicry.html

6. 5Biomimicry Biomimicry (or Bionics, Biomimetics, or Biognosis) “Life has been performing design experiments on Earth’s R&D lab for 3.8 billion years. What’s flourishing on the planet today are the best ideas---those that perform well in context, while economizing on energy and materials. Whatever your company’s design challenge, the odds are high that one or more of the world’s 30 million creatures has not only faced the same challenge, but has evolved effective strategies to solve it.” http://www.biomimicryguild.com/indexguild.html

13. 12Biomimicry Glue Clues from Geckos A team of biomedical engineers and materials scientists at Northwestern U have developed a glue inspired by both Geckos and Mussels They mimic the microscopic hairs of the gecko but add a protein that mimics a protein the mussel uses to adhere to wet surfaces The result is a post-it note type of adhesive that works on wet or dry surfaces, even after being pulled away and reattached more than 1000 times “Glue Clues From Geckos,” Discover Magazine, January 2008.

18. 17Biomimicry bioWAVE bioWAVE was created by BioPower systems. bioWAVE is a hydroelectric system that mimics the motion of plants, particularly kelp, to allow for maximum energy absorption. The motion of the waves move the fins, which turns a generator. Systems are being developed for 250kW, 500kW, 1000kW capacities to match conditions in various locations.

26. 25Biomimicry Bio-Inspired Ceramics Ceramics are lightweight and hard, but you can't make jet engines or automotive frames out of them because they'd shatter like dinner plates. Materials scientists have looked to the porous but resilient material called nacre that lines abalone shells and have developed a method for manufacturing nacre-like materials in the lab. The new method could lead the way to ceramic structural materials for energy-efficient buildings and lightweight but resilient automobile frames.
