Last week was Spring break and we had this great opportunity of going and presenting in digiFAB conference in Boston about Biomimicry through one of my Sponsors TIES! Lots happened and I was excited to meet some great people in the field and had butterflies about my own talk. My excitement was doubled and butterflies gone with keynote speaker, Sherry Lassiter director of Fab Foundation, You can see her in picture below talking about different movements within Fab Foundation as well as the Fab network.
Dale Dougherty, then talked about Maker movements, I have been following Dale’s maker group (he runs the Make: which you can subscribe to) and was thrilled when he talked about “Autonomous Boat [that] Went from California to Hawaii and Beyond”. I read about this project when first published in Make: and was happy that the boat had been picked up by a ship in New Zealand and was in display there.
The 2 day conference was packed by amazing talks, I like to shortly go through few of them.
FAB City A 40 year goal from Barcelona to empower citizens to be creators of their own city; “locally self-sufficient and globally connected”. For me, it seemed as a society that doesn’t need a centralized governing body, but where citizens create materials based on their needs, recycle when possible and are connected to many more cities around the globe.
Tomas Diaz from FABCity also talked about the model and plans they have to reach this goal in Barcelona. he talked about POBLENOU where its supported by local and international community to become a FAB city.
Rachel Ignotofsky; Women in Science , and the importance of design and arts in our life, how arts influences our perceptions and why is it important to use it in our learning kits.
3D printes, bluedragon made with business in mind, where you can print 4 colors in one product, you can mix different colors into one or just use one at a time: FIREPRINT. If anyone wants to put money together to get one, I am in! Check out their case studies, from combating Zika to cosplay, you can do all!
Second day was nothing short of amazing talks as well, we first heard from Neil Gershenfeld, Director, MIT Center for Bits and Atoms, of his work on developing tools/processes for FABLAB, I did not see it coming where he talked about Nature! In below picture he was explaining how creating modules is similar to protein formation in our body.
He also talked about how we are moving to Ubiquitous and with these changes, how his lab is working on developing the tools, materials, to functional part.
And one of my favorites; Global Humanitarian Lab, talk by David Ott, Co-founder, Where they aim to bring FABKits (costing around < $10k) to refugee camps. David talked about what would be in the FABKits and how everything needs to be packed into container that could be transferred by 1 or 2 person. He talked about limitations, needs and potentials of these labs. He talked about makers/ people who need the opportunities we easily can access in our cities.
There was many more talks which I highly recommend attending. This year, there was an addition of having workshops and we had ours on Biomimicry in Artisan’s Asylum in Somerville. Another place to put in your places to go!
So What did we talk about! We talked on first day about Spiders and Ornilux, Tardigrades, Spikemoss and Stabilitech/Biomateria and How they relate to maker group! As we grow in FAB network and as we move toward FAB cities, Can we benefit from nature’s stories? Can we learn from 3.8 billion years of lessons? Our hope is to learn and make more sustainable decisions. Either in creating new FAB equipments, or materials used. We see a movement that will grow potentially in years to come and we want to instill biomimicry thinking in its foundation!
“Plants are amazing!” This is something I hear a lot from non-botanists. Of course, I know plants are awesome, but every time I turn around, I learn something new and exciting. This semester was no exception. Tasked with a project in my Biomimetic Design class, led by Dr. Petra Gruber, I walked into the meadow to find inspiration– literally.
On a very wet, cold, rainy day in October, I walked to a meadow within our field station property (Bath Nature Preserve, Bath Twp., Akron, Ohio) and found a section to investigate. Indian grass (Sorghastrum nutans) towering over my head, I decided to stop at 20 steps and set up a 1m x 1m plot to sample. October in a meadow doesn’t give you very much to identify, but goldenrod (Solidago spp.) and Indian grass (S. nutans) were plentiful among a few baby asters, Galium spp. (aka ‘Cleavers’ or ‘Bedstraw’), wild strawberry (Fragaria virginiana),clumps of unidentifiable grass and moss. I measured heights of stems and area covered, took the percent coverage to determine how much each species covered the plot,and took several picture views for record. After returning to campus, I created a hand-drawn schematic of the plot.
A few weeks later, I returned to the same plot. Apparently my methods of counting and direction are spot-on because my last step landed on a pen I had dropped on that rainy day a few weeks earlier! If you’ve ever done field work, you understand how amazing it is that I found a PEN in the middle of a meadow over 2 meters high! This time I was there to measure the ability of the meadow to hold a load. I admit, I didn’t think the stems would hold up… being so late in the year and being dried out. As usual, though, plants are amazing and surprised me yet again!
I decided to test the load by creating a 1m x 1m foam board that was sturdy, yet lightweight. I placed the board directly over the plot, placing flags on each corner. The flags allowed for a visual cue to observe movement of bot
h plants and the board, as well as giving a reference point at which to measure the height of the board after each addition of weight. After the foam board was placed on top of the plants, I measured the height at each corner (flag) for the “initial” height. I added one heavy book and measured the height at each corner. Subsequently, I added increasing weight and measured the heights. At 3 books (6.7kg), the system (the meadow plot) could no longer hold the weight. Because this was the same plants were used over the entire experiment, I believe more weight can be held by the plants in true form.
So how does this happen? Plants are amazing. In the meadow, plants grow up to 10 feet below ground (roots) and above ground. You can imagine how secure this makes these cantilever beams! Here, the Indian grass and Goldenrod grew 1.5m to 2.5m above ground. The stems reached diameters of 2-5mm. You may wonder how the stems did not break when the weight was added. Galileo was the first to record these observations, noting that bending is resisted in the outer layers, not the inner stem as some might think. Several studies have investigated this design, including F.O. Bower (1930) who compared plant stems to concrete, saying, “Ordinary herbaceous plants are constructed on the same principle. The sclerotic strands correspond to the metal straps, the surroundin
g parenchyma with its turgescent cells corresponds mechanically to the concrete.” Equisetum (Horsetail) is another champion plant for many reasons, but here, in this context, it’s a biomechanic superstar. “The hollow stem of Equisetum giganteum owes its mechanical stability to an outer ring of strengthening tissue, which provides stiffness and strength in the longitudinal direction, but also to an inner lining of turgid parenchyma, which lends resistance to local buckling. With a height >2.5 m isolated stems are mechanically unstable. However, in dense stands individual stems support each other by interlacing with their side branches, the typical growth habit of semi-self-supporters.” (Spatz, Kohler, Speck 1998). Again, plants are amazing.
After doing some mathematical calculations (very much estimated
in this case because of the imprecise nature of this ‘experiment’), it is expected that a single Goldenrod stem can support >118% of its biomass! Now, we’re not talking about the strength of steel or lead, but we can see that plants offer us new possibilities when we are designing or constructing new things! Imagine a support feature that is hollow inside and allows for storage in the “stem” as well has having the strength to support weight. Think on a smaller scale: imagine a space in which a stiff, lightweight outer covering is needed to secure something. Imagine the many possibilities that plants offer us to grow using Life’s Principles.
Biomimicry is a tool/discipline that can be used in many fields ranging from industrial design, architecture, engineering, math, and even computer science. Being from a graphic design background and practicing digital painting, I find myself struggling to find exactly where biomimicry fits within the digital aesthetics realm. Can a designer/artist practice digital arts in a biomimetic way, or are the digital arts just a good tool to perform and carry out biomimetic thinking within a digital space? Surely when you are 3D modeling a biomimetic building or product on your computer, you are aiding in the biomimetic design process, but the 3D modeling process itself isn’t the thing that is biomimetic, is it? Biomimicry, in root words terms, is the act of mimicking life. How literally should we take this? Is virtual reality a sort of biomimicry because it does just that; mimics life? Maybe it’s just a useful tool to aid in the design process. These are some of the things I hope to figure out in my studies, but I’m finding as I dig deeper that when approaching biomimicry with a digital aesthetics lens, that it’s not just about the design process and appearance, but also about how using digital tools can help learn or experience something in the natural world. It is possible that, like art, digital aesthetics is particularly useful to inspire, evoke emotions, and increase understanding using the natural world as a muse. Continue reading
