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.”

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.”

8Biomimicry Termite Thermal Regulation Incredible ability of termites to maintain virtually constant temperature and humidity in their Sub-Saharan Africa despite outside temperature variation from 3 °C to 42 °C Project TERMES (Termite Emulation of Regulatory Mound Environments by Simulation) scanned a termite mound, created 3-D images of the mound structure and provided the first ever glimpse of construction that may likely change the way we build our own buildings The Eastgate Centre, a mid-rise office complex in Harare, Zimbabwe, stays cool without air conditioning and uses only 10% of the energy of a conventional building its size

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.

16Biomimicry Fishbone Audio Sensor Tokyo Electron has created the fishbone sensor, a new type of audio sensor using the inner working of the human ear as a model Each of the 24 cantilevers of the fishbone sensor works like a human ear membrane and picks up individual frequencies

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.

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.

26Biomimicry Bio-Inspired Ceramics (Cont.) The Berkeley ceramic "really shows that drawing our inspiration from nature in order to synthesize better materials can be very successful," says Julia Greer, a materials scientist at CalTech.

29Biomimicry How to Think Like a Biomimic Determine what you want to “do” (not “make”) Identify key functions/purpose Look to see how nature achieves those functions Go observe nature’s genius and conduct research or talk to experts to find patterns or principles which may work for your problem Brainstorm, design and converse Refine the design Source: Biomimicry Guild, La Cusinga, Costa Rica Design Workshop, 2007
