Scientists Have Created Self-Healing Fabrics that Also Protect from Harmful Chemicals

Scientists Have Created Self-Healing Fabrics that Also Protect from Harmful Chemicals | Biomimicry | Scoop.it

2Protective clothing is critical to the health and safety of workers who handle hazardous chemicals. A new fabric coating promises to not only neutralize toxins, but also to heal tears and holes on its own while the clothes go through the laundry. The coating, developed by a team of researchers from Penn State and Drexel University, is derived from proteins that make up the rings of teeth on squid suckers."

Dutch Scientists Create Concrete that Heals Itself With Built-in Bacteria

Dutch Scientists Create Concrete that Heals Itself With Built-in Bacteria | Biomimicry | Scoop.it

"Scientists in the Netherlands have created a bio-concrete blend with built-in bacteria that can patch up small cracks and holes in cement. Activated by water, the bacteria would eat food provided in the concrete mixture to combine calcium with oxygen and carbon dioxide to form what is essentially limestone."

Healing Plastics And Reconnecting Circuitry. Biomimicry At It's Finest

Healing Plastics And Reconnecting Circuitry. Biomimicry At It's Finest | Biomimicry | Scoop.it

"A fascinating new programme highlights how new materials are being manufactured that can actually heal themselves. From ByteSizeScience – “Our latest episode explores materials that mimic the human skin’s ability to heal scratches and cuts. For a first-hand look at self-healing plastics, we visited the lab of Nancy Sottos, Ph.D., professor of engineering at the University of Illinois at Urbana-Champaign. Inspired by human skin, the plastics repair themselves by “bleeding” healing agents when they are cut or scratched. This research offers the promise of cell phones, laptops, cars, and other products with self-repairing, longer-lasting surfaces.”"

Vascular Networks Make Self-healing Possible in Composites

Vascular Networks Make Self-healing Possible in Composites | Biomimicry | Scoop.it

"One of the more intriguing capabilities in nature is, however, the number of biological systems that are able to self heal. Scientists, spurred on by the potential economic benefits of materials that would be able to repair themselves  - longer lifetime, lower maintenance costs and more efficiency - have worked to develop self-healing systems for various materials, including plastics. And with success: various polymers are now available which have  the intrinsic ability to repair damage caused by usage over time. Up until now, however, composites, were a whole different ballgame. But once again, nature showed the way."

The Next Frontier in Design? Hierarchical Structures

The Next Frontier in Design? Hierarchical Structures | Biomimicry | Scoop.it

"Natural hierarchical systems share some common traits that are worthy of emulation: They use a few components (like keratin) to make a wide array of different structures in controlled orientations with durable interfaces between different materials. They are dependent or sensitive to water and produced with benign chemistry. Their properties and performances can vary in response to the environment. These complex, controlled shapes are resilient and often are able to repair themselves."

Self-healing Solar Cells Mimic Leaves

Self-healing Solar Cells Mimic Leaves | Biomimicry | Scoop.it

"Solar cells based on organic systems have the potential to become less expensive and more environmentally friendly than silicon-based solar cells, the current industry standard. But the sun’s ultraviolet rays deteriorate  their performance. Now North Carolina State University researchers Orlin Velev and Hyung-Jun Koo have designed solar-cell devices with channels that were inspired by the branching vascular channels that circulate life-sustaining nutrients in leaves and human hands."

Mimosa Biomimicry Inspires New Adaptive Structures

Mimosa Biomimicry Inspires New Adaptive Structures | Biomimicry | Scoop.it

Researchers at University of Michigan (U-M) and Penn State University are studying how plants like the Mimosa can change shape, and they’re working to replicate the mechanisms with artificial cells. Currently, their artificial cells are palm-size and larger, but they’re trying to minify them by using microstructures and nanofibers to construct them. They’re also exploring how to replicate the mechanisms by which plants heal themselves.

Bacteria Could Grow Futuristic 'Self-Healing' Materials

Bacteria Could Grow Futuristic 'Self-Healing' Materials | Biomimicry | Scoop.it
Living materials produced by bacteria could lead to interactive structures programmed to self-assemble into specific patterns, such as those used on solar cells and diagnostic sensors, and even self-healing materials that could sense damage and repair it.

Synthetic Gel Mimics Amphibians' Ability to re-grow

Synthetic Gel Mimics Amphibians' Ability to re-grow | Biomimicry | Scoop.it

"Engineers at two universities in Pittsburgh have copied the way amphibians regenerate their body parts in the model for the synthetic gel. [...]  The ability of amphibians to re-grow a limb or a tail was a "truly a remarkable thing", Ms Balazs said. She added: "You can mimic in a synthetic material something that happens in biology. It does not even happen in human beings, really."
