The innovative architect and designer Felecia Davis can make buildings out of wool and fungus.
More on human ingenuity today. At the Washington Post, Elizabeth Evitts Dickinson writes about a woman who is pioneering all-fiber construction materials and “clothes that monitor your health.” And that’s just the beginning.
“Imagine you’re standing in an outdoor pavilion,” Dickinson suggests, “one that’s similar in design to a covered picnic area at a local park or an amphitheater, only instead of support columns made from concrete, wood or stone, this structure is propped up by what appear to be posts of crocheted wool. Above you, a vast expanse of undulating roof is made of the same knitted material. Fungus coats this wool frame, forming the walls and the ceiling, not unlike the way plaster might cover the wood framing of a wall.
“This is the premise of an experimental material known as MycoKnit. ‘We’re trying to make an all-fiber building,’ says designer Felecia Davis, an associate professor of architecture and a lead researcher in the Stuckeman Center for Design Computing at Pennsylvania State University. She is part of an interdisciplinary team testing how knitted materials, such as wool yarn, might function as the framing for a building while a mixture of straw and mycelium fungus embeds itself onto this knitted fabric to create the rest. Mycelium is composed of individual fibers known as hyphae, which, in nature, create vast and intricate networks through soil, producing things like mushrooms. The amazing thing, Davis tells me, is that something as basic as fiber can become both the structure (the wool yarn) and the infill (the fungus).
“Davis and her partners are harnessing mycelium’s fast-growing power by regulating environmental conditions in the lab to encourage the fungus’s expansion on their knitted edifice. With the assistance of a computer algorithm made by one of Davis’s PhD students, the team can virtually assemble and examine the structure stitch-by-stitch in order to predict its shape, before building it and letting the fungus propagate overtop. …
“Davis is now working with her students to create a 12-by-12-by-12-foot MycoKnit prototype that can be fabricated and grown in one place, and then taken on-site to build, like an Ikea kit. She imagines a future where biofabricated materials replace less-sustainable building supplies, many of which wind up in landfills.
“Davis is a triple threat designer: trained as both an architect and an engineer, and with a penchant for technology. In her Penn State lab and through her firm, Felecia Davis Studio, she mixes time-honored craft techniques and humble materials with the high-tech — so that clothing might, for instance, alert the wearer to excess carbon monoxide in the air or signal when an infant stops breathing in their crib. Davis works with textiles, she says, because ‘you can address it at the nano- and micro-scale with tiny particles that you can spin to make a thread or yarn, or you can look at it from the massive scale. A building. A city.’ …
“Davis has always loved experimenting with objects and material. The oldest of three siblings, her earliest collaborator was her sister Audrey (now a neonatologist). As kids in the ’60s and ’70s, they explored the foothills of Altadena, Calif., near their home, gathering fresh bay laurel leaves and other natural materials for projects. With their friends, they fashioned dolls out of flour-based papier-mâché, carving apples for the heads. …
“Davis’s mother volunteered at the Pasadena Art Museum and introduced her children to abstract art and modernism; she was also a docent at the Gamble House in Pasadena, one of the country’s most well-preserved examples of Arts and Crafts design. Davis credits that house, in part, for her early desire to pursue architecture. ‘We would do our homework in the attic while she gave her tours,’ Davis says. ‘That house was mind-blowing.’
“On a recent October day, the SoftLab at Penn State is ‘messy,’ Davis says. … Fabric samples have been stretched and pinned to a corkboard, sharing space next to thin electrical conduits and sketches of networking design. There are clear boxes filled with copper-coated yarn and fabrics twisted with stainless steel that are capable of conducting electricity. Davis is refreshingly agnostic about her sourcing, using a combination of existing craft techniques and materials — from wool to human hair — in combination with the latest in software and hardware, such as the LilyPad Arduino, a microcontroller designed to work with e-textiles.
“A pair of black leggings stretch across the bottom half of a dress form. From a distance, they resemble something a rock star might wear, bedazzled and tricked out with lines of metallic thread, but on closer inspection these accents are electrical threads and processors. The leggings are the result of a partnership with Penn State engineer Conrad Tucker, who wanted to create a way of alerting people with Parkinson’s disease to subtle changes in their walking gait, which can foreshadow the onset of more debilitating symptoms. …
“The leggings were originally an information-gathering experiment, but ‘we’ve circled back on this project now that we have a yarn that is washable,’ she says. ‘We think we can make a simpler version of our leggings.’ Davis sees the potential for other ‘smart’ clothing like
a hospital shirt that frees patients from the tether of wires affixed to machines, allowing them to move freely or, ideally, go home sooner because their clothes, connected to the internet, would be able to communicate critical data to doctors.
“While Davis was earning her master’s in architecture at Princeton University, she ‘noticed how little people talk about the emotional experience of people in [a] space. … You’re in basic response with your environment all the time … You’re meshing with it, which is why it’s so important to think about human emotion in design.’ In this view, the aesthetics of what we design is more than an accessory, but a fundamental need in support of human emotional health. …
“As humans we tend to imbue the materials in our lives with emotional resonance — a child’s security blanket or a favorite sweater — and Davis has wondered whether we could also imbue the materials themselves with emotional feedback capacities. In 2012, she partnered with two other designers to create and install a project called the Textile Mirror at Microsoft Research Lab in Redmond, Calif. In the back of a fabric panel, Nitinol wires, made of a shape-changing nickel-titanium alloy, were activated after a person entered information about their state of mind into a mobile phone. The panel would adjust, shrinking and crumpling to reflect pain or sadness, for instance, and then release. As the textile ‘relaxed,’ it helped those in an agitated state to relax as well. Textiles capable of reflecting emotion have the potential to alert architects, building owners and inhabitants to the effect that specific design and material choices have. We can begin to create emotionally reactive dwellings and objects, as Davis calls them. …
“As someone who believes in the scientific method of showing data and results, Davis recognizes that working with emotions is tricky. It’s nearly impossible to scientifically pin down, precisely, what people are feeling at any given time. ‘This is kind of at the edge of what computation can actually tell you,’ she says. ‘We can’t read people’s minds, and yet we function as a species because we can intuitively read emotions.’ “
