  1. Affirmed We are fearfully and wonderfully MADE “I am fearfully and wonderfully made;Wonderful are Your works,And my soul knows it very well.” - Psa 139:14, NASB - What is made REVEALS A CREATOR of eternal power and divine nature “For since the creation of the world His invisible attributes, His eternal power and divine nature, have been clearly seen, being understood through what has been made, so that they are without excuse.” - Rom 1:20, NASB - The Creator is not like His creation, because HE IS GREATER AND WISER than the pinnacle of His creation, mankind “Because the foolishness of God is wiser than men, and the weakness of God is stronger than men.” - I Cor 1:25, NASB -

  2. Biomimetics Imitation of Life

  3. Definition • biomimetics: - The study of the structure and function of biological systems as models for the design and engineering of materials and machines. (American Heritage) • biomimetics: – man’s attempt to copy features of God’s creation to improve his own designs (Stevens) “Imitation is the sincerest form of flattery”

  4. For Example… • 1941 Georges de Mestral • Velcro http://en.wikipedia.org/wiki/File:Micrograph_of_hook_and_loop_fastener,(Velcro_like).jpg http://en.wikipedia.org/wiki/File:Bur_Macro_BlackBg.jpg

  5. Areas of Research MechanicsProcessesMaterials

  6. MECHANICs

  7. EnvironmentalControls The Eastgate building in Harare, Zimbabwe uses 10 % of the energy of similar buildings its size. How? By learning from termites. 37 to 108 °F outside? No problem. 87.8 +/- 1 °F inside, day or night. http://biomimicryinstitute.org/case-studies/case-studies/termite-inspired-air-conditioning.html

  8. Bumpy humpbacks • Tubercles • One article discussing this - entitled “Evolution meets Creation” • Reduces drag by 32% http://www.mnn.com/earth-matters/wilderness-resources/photos/7-amazing-examples-of-biomimicry/whale-turbine http://www.sustainableindustries.com/articles/2009/07/evolution-meets-creation

  9. Counter-Intuitive Approach • How to reduce the pain of an injection? • Same as avoiding pain from a mosquito “bite” • Add serrations!

  10. Agile Blowflies “With wings beating 150 times per second, it hovers, soars, and dives with uncanny agility. From straight-line flight it can turn 90 degrees in under 50 milliseconds —a maneuver that would rip the Stealth fighter to shreds.” “The key… isn’t to attempt to copy the fly, but to isolate the structures crucial to its feats of flying, while keeping a sharp eye out for simpler—and perhaps better—ways to perform its highly complex operations. ‘The fly’s wing is driven by 20 muscles, some of which only fire every fifth wing beat, and all you can do is wonder, What on Earth just happened there?’ says Fearing. ‘Some things are just too mysterious and complicated to be able to replicate.’” • Tom Mueller, “Biomimetics: Design by Nature.” National Geographic. April, 2008 • http://ngm.nationalgeographic.com/2008/04/biomimetics/tom-mueller-text/1

  11. Climbing the Walls “Stickybot now walks up vertical surfaces of glass, plastic, and glazed ceramic tile…. For the moment it can walk only on smooth surfaces, at a mere four centimeters per second, a fraction of the speed of its biological role model. The dry adhesive on Stickybot’s toes isn't self-cleaning like the lizard’s either, so it rapidly clogs with dirt. “There are a lot of things about the gecko that we simply had to ignore,” Cutkosky says.” http://ib.berkeley.edu/alumni/postcard_5.php http://ngm.nationalgeographic.com/2008/04/biomimetics/tom-mueller-text/2 http://sites.duke.edu/dukeresearch/files/2012/11/TokayFoot2-KA.jpg

  12. Processes

  13. Efficient Lighting • Incandescent bulbs LOSE 98% of energy as heat • Glow worms USE almost 100% of energy when generating light • Glow worms also use fiber optics to transmit the light and matching IOR droplets to release it and catch prey • Fireflies (also very efficient) have scales to improve reflection • Implementations with LEDs have increased light transmission by 33% http://ngm.nationalgeographic.com/2008/04/biomimetics/tom-mueller-text Bar-Cohen, Yoseph.

  24. Army 2008 - Bio-Inspired Battlefield Environmental Situation Awareness One more example “OBJECTIVE - Autonomous and semi-autonomous systems often run afoul of the battlefield environment. Small and micro air vehiclesdesigned to operate in urban environments, or inside vegetative canopies, are at considerable riskfrom wind gusts that may blow them into obstacles (Weiss, 2007).”

  25. “Biological systems like hummingbirds and dragonflies cope quite well with such conditions. Many types of autonomous systems face hazards similar to those faced by biological systems of comparable size - running into dangerous objects, getting stuck, falling into holes, drowning, etc. “Such mechanisms typically involve sensing and response to the environment - applied situation awareness. The objective of this topic is to investigate one or more of such environmental situation awareness mechanisms and find the applicable biological adaptations for coping with the hazard, and ultimately, develop that mechanism for use by Army autonomous systems.”

  26. “DESCRIPTION - The world is populated with a seemingly countless number of tiny machines that exhibit very complicated adaptive behaviors in challenging environments – living creatures. “Even very tiny and simple creatures manage to solve the problem of sensing their environment and control of motion and flight in a turbulent atmosphere.They do this with the aid of neural systemsthat are nearly microscopic. “There is more than one reason that this effectiveness is surprising. They perform their information processing… roughly one million times slower than the comparable numbers for a modern silicon based microprocessor.”

  27. “These processing elements arethemselves living systems(neurons and associated cells) that need to ingest food, synthesize a variety of products they need for life and function and cooperate with other similar systems. “Moreover, they are exquisitely delicate– temperature and their biochemical environments need to be precisely controlledin order for them to function. “Human engineers, at least for the moment, are quite incapable of building something as small and complex in its behavior as a fly, despite the apparently very great advantages of our information processing technology. The most plausible explanation for this unreasonable effectiveness is... … superior design.”

  28. Is it design, or isn’t it? “But the main reason biomimetics hasn’t yet come of age is that from an engineering standpoint, nature is famously, fabulously, wantonly complex. Evolution doesn’t “design” a fly’s wing or a lizard’s foot by working toward a final goal, as an engineer would—it blindly cobbles together myriad random experiments over thousands of generations, resulting in wonderfully inelegant organisms whose goal is to stay alive long enough to produce the next generation and launch the next round of random experiments. To make the abalone’s shell so hard, 15 different proteins perform a carefully choreographed dance that several teams of top scientists have yet to comprehend. The power of spider silk lies not just in the cocktail of proteins that it is composed of, but in the mysteries of the creature’s spinnerets, where 600 spinning nozzles weave seven different kinds of silk into highly resilient configurations.” http://ngm.nationalgeographic.com/2008/04/biomimetics/tom-mueller-text/2

  29. “The multilayered character of much natural engineeringmakes it particularly difficult to penetrate and pluck apart. The gecko’s feet work so well not just because of their billions of tiny nanohairs, but also because those hairs grow on larger hairs, which in turn grow on toe ridges that are part of bigger toe pads, and so on up to the centimeter scale, creating a seven-part hierarchy that maximizes the lizard’s cling to all climbing surfaces. For the present, people cannot hope to reproduce such intricate nanopuzzles. Nature, however, assembles them effortlessly, molecule by molecule, following the recipe for complexity encoded in DNA. As engineer Mark Cutkosky says, “The price that we pay for complexity at small scales is vastly higher than the price nature pays.” http://ngm.nationalgeographic.com/2008/04/biomimetics/tom-mueller-text/2
