Learning from Nature: the Beauty & Value of Biomimicry: Sustainable innovation inspired by nature is not new, but it's never been more relevant.
That was the message delivered last month by Seth GaleWyrick, senior mechanical engineer and sustainable design specialist at Bresslergroup, at SPE's second Design in Plastics conference, held Nov. 6 to 8 at the College for Creative Studies in Detroit.
GaleWyrick, who lives in Montana, has worked for 12 years at the 65-person, Philadelphia-based design firm, and has spent the past three years studying biomimicry--which is simply a tool set for innovation based on learning from biology. He is currently two years into pursuing both his Master's degree and professional certification in biomimicry. He is one of 18 students in the first-of-its-kind program being offered online by Arizona State University.
The track record for new product development is under-whelming: 25 to 45 percent of new goods fail, according to the Product Design & Marketing Association, and 95 percent of all new products miss their targets, according to the U.S. Department of Commerce. And that doesn't even account for all the goods that never make it to market.
So, GaleWyrick asked the audience, "What if relying on only human cleverness is holding us back?" The first organism appeared on this planet some 3.8 billion years ago, and life has been evolving solutions to most of our problems ever since.
'That's the promise of biomimicry," notes GaleWyrick. Instead of looking at a problem and asking, 'Have we done this before?', he suggests we ask a biologist if something else has done this before. The design solutions found in the natural world are so beautiful, elegant, and functional that designers and engineers should truly be inspired.
Here are just a couple examples:
Swimming with the sharks: Container ship hulls are a magnet for barnacles and bacteria growth and the like. World-wide, these organisms combined cost companies an estimated $67 billion a year due to extra drag they create. It's a problem that's been addressed many times in the past few hundred years, usually by coating ships with a wide range of incredibly toxic substances--typically heavy metals--that basically kill everything they touch. But does that seem like a good idea for things floating in the same ocean that generates half the oxygen on earth and that provides much of the seafood that we humans consume?
Ask a marine biologist. It turns out that sharks have been working on this same problem for more than 400 million years. These fish have developed geometrically shaped scales with tiny ridges that create micro vortices that inhibit the growth of biofilms. Bacteria and algae cannot colonize and spread on such structures, due to the shape, with the result that this "design" also serves to reduce drag. Sharks couldn't afford to poison the ocean where they live, so they evolved a more elegant, efficient solution, one that is in the process of being adopted on airplanes and ship hulls, and even in hospital settings, to help minimize the spread of hospital-acquired infections.
Taking the sting out of your injection: The design of the modern hypodermic needle seems counterintuitive. It features a series of very tiny bevels that, when magnified to the human eye, look like a nasty saw blade with a painful jagged edge. But these bevels make the blade sharper and more comfortable while sliding through the skin. Entomologists studied mosquitos to determine how they manage to pierce your skin while barely being detected. It turns out that, at this scale, the points actually trigger far fewer nerve endings and you barely feel the jab.
These are examples that offer an obvious, direct translation to human needs. But biomimicry is rarely this direct.
Making PHA resin, naturally
Take the work being done by Newlight Technologies Inc. of Costa Mesa, Calif. Microbiologists in the 1980s discovered there are microorganisms that naturally generate a type of plastic called polyhydroxyalkanoate, or PHA, in their cells. This initially generated a lot of excitement, but research failed to find a way to commercialize this bioresin cost-effectively.
Founded in 2003, after 10 years of research, Newlight (www.newlight.com) says it has "developed, patented, and commercialized the world's first commercially scaled carbon-capture technology able to produce high-performance thermoplastics from air and methane emissions that can match the performance of oil-based plastics and out-compete on price."
The firm's resulting PHA material, called AirCarbon, combines air with methane-based carbon emissions--carbon that would otherwise be part of the air we breathe--to produce a material that is approximately 40 percent oxygen from air and 60 percent carbon and hydrogen from captured methane emissions by weight. They claim it costs less than oil-based thermoplastics.
In March 2016, IKEA Group--the Swedish home-furnishings giant--announced it had entered into a 10 billion-pound supply, collaboration, and technology license agreement with Newlight that will provide IKEA with AirCarbon from the California firm's commercial-scale production facilities and enable IKEA to produce AirCarbon thermoplastic under a technology license.
Under the agreement, IKEA said it will purchase half the material from Newlight's 23,000-tonne-per-year plant in the United States, and subsequently IKEA has exclusive rights in the home furnishings industry to use Newlight's carbon-capture technology to convert bio-based greenhouse gases, first from biogas and later from carbon dioxide, into AirCarbon thermoplastics for use in its home furnishing products.
The two firms have a long-term goal to develop capacities up to 1 billion pounds peryear. IKEA's aim is for all the plastic material used in its home furnishing products to be renewable or recycled material.
Coining the phrase
Biomimicry literature is full of thousands of cases studies and those are just the ones identified since author and innovation consultant Janine Benyus coined the term 20 years ago. New Jersey-born Benyus is the foremost expert on this topic, and wrote the first of her six books in 1997, called Biomimicry: Innovation Inspired by Nature.
In a 2009 TEDGlobal Talk, she said: "We live in a competent universe. We're part of a brilliant planet, and we are surrounded by genius. Biomimicry is a new discipline that tries to learn from those geniuses, and take advice from them, design advice."
She currently runs Biomimicry 3.8 (https://biomimicry.net), her for-profit consulting company, and the Biomimicry Institute (https://biomimicry.org). a Missoula, Mont.-based nonprofit she co-founded in 2006 with Bryony Schwan. The latter also hosts an interactive informational website called AskNature.org (www.AskNature.org).
About woodpeckers and concussions
A team at Priority Designs in Columbus, Ohio, meantime, has been following Benyus' advice. Jamison Float, senior biomedical engineer at Priority, is leading the project to create a device designed to mitigate the effects of concussions through biomimicry.
Float, who also spoke at the recent Design in Plastics conference, said there are 3.8 million sports-related concussions in the United States each year, and that brain injuries are also a major issue for the military.
He explained how Dr. David Smith, an internist with a degree in chemistry, began researching the issue after being challenged by a U.S. military general to figure out why woodpeckers--which hit their heads 80 million times over a lifetime--don't get concussions. After a year of study, Smith realized the woodpecker activates the omohyoid muscle in its head upon impact to apply slight pressure on the jugular, which slightly increases blood volume in the brain, creating a sort of cushion.
When the head experiences an impact of extreme force, "slosh" is the movement of the brain as it is floating in the cerebrospinal fluid inside the skull. As the brain sloshes inside the skull it can rotate or strike the walls of the cranium, often tearing brain fibers resulting in mild traumatic brain injury (mTBI). An extreme force to the brain can result in concussion, but smaller, repeated impacts can lead to chronic traumatic encepelathopy (CTE), which is a form of brain damage resulting in dementia.
Humans also have an omohyoid muscle, but little was understood about what it did. Over the next seven years, neurosurgeons, researchers, engineers, and designers performed extensive research to determine how to replicate the action of the woodpecker's omohyoid. The team faced challenges that included how to deliver the appropriate pressure, material and fit. Using a variety of existing and emerging medical technologies, they tested prototype device after device to verify safety and efficacy.
Smith then convinced neurosurgeon Dr. Julian Bailes, who is a former Pittsburgh Steelers physician and a character portrayed in the 2015 football movie "Concussion" starring Will Smith, to test his jugular-constriction theory by using the device on rats. The study revealed an astonishing 83 percent reduction of concussion-related protein development in the rats' brains, whereas previous methods of protection had resulted in a change of no more than 5 percent.
Excited by the results, Smith licensed the technology to a small, Westport, Conn.-based sporting goods and medical device manufacturer named Q30 Innovations LLC (www.q30innovations.com), which already worked with Priority Designs and asked them to join the project.
Extensive further testing and development followed. Designs were careful to reduce or eliminate pressure on the trachea as not to interfere with breathing. The solution was a C-shaped collar with a curved profile to keep the device low on the neck. It applies slight pressure to the neck that mildly increases blood volume in the brain to create a cushion that reduces movement of the brain inside the skull.
The resulting product--dubbed the Q-Collar--addresses the problem from the inside out by mimicking the woodpeckers' natural defense. Priority describes it as "the world's first technology to use the body's natural physiology to protect against mild traumatic brain injury caused by concussive events."
Extensive (and ongoing) testing has confirmed the safety benefits of the Q-Collar, while also demonstrating it has no negative effects on the wearer's performance, effort or response time.
Priority Designs has worked closely with Q30 Innovations to transfer the device to manufacturing for commercialization, and is partnering now with Sussex, Wis.-based injection molder Sussex IM. The Q-Collar is currently in production with a Canadian launch for late 2017 as it undergoes review in the U.S. by the Food & Drug Administration.
Editor's Note: Arizona State University (Master's program) and the University of Akron (Ph.D. program) are the only two U.S. schools that currently offer degrees in biomimicry. Additionally, the Minneapolis College of Art & Design, the University of California --Berkley, and the Savannah College of Art & Design also offer biomimicry courses.
