A new 3D printed gel that can heal like living tissue, and change form in response to environments, has myriad applications from fixing cracked phone screens to adaptive camouflage
“When I was young, my idol was Wolverine from the X-Men…He could save the world, but only because he could heal himself,” researcher Chao Wang recently said in a press release from the American Chemical Society (ACS). Wang began working on a self-healing material that could stitch itself back together after damage, and came up with a game-changing polymer.
The key to the the material’s crucial new powers? Chemical bonds. Check out this video.
The new Electrical Prescriptions (ElectRx) (pronounced “electrics”) DARPA program aims to develop new high-precision, minimally invasive technologies for modulating nerve circuits to restore and maintain human health, initiated in support of the President’s brain initiative.
The newly-developed self-healing plastic can take rather extensive damage and heal it through a process of regeneration.
There are several self-healing substances in the world, ranging from the LG G Flex’s scratch-healing casing to Stanford’s synthetic self-healing skin. A plastic developed by the University of Illinois is one of the latest plastics developed that regenerates when damaged.
MIT has had a number of off-the-wall discoveries, so it takes something truly unexpected to throw the researchers there for a loop. MIT researchers have recently discovered the self-healing properties of metal. If their discovery means what we think it means, we could just have witnessed to the birth of the T-1000.
Self-healing artificial leaf.
Scientists reported the creation of the “world’s first practical artificial leaf” back in 2011. The leaf mimics the ability of real leaves to produce energy from sunlight and water. Touted as a potentially inexpensive source of electricity for those in developing countries and remote areas, the leaf’s creators have now given it a capability that would be especially beneficial in such environments – the ability to self heal and therefore produce energy from dirty water.
Self-healing, squishy hydrogels
One of biology’s greatest tricks is the ability to heal–to repair oneself repeatedly and thus sustain damage repeatedly, and one that humans have been trying to replicate in synthetic materials for years. Now, bioengineers at University of California, San Diego, have done so via a hydrogel that could be something of a game-changer in disciplines like medicine and materials science.
It would be great if you could take your car to the body shop and have it repaired in minutes, before your eyes, without anyone even laying hands on it. There have been several developments in self-healing coatings recently.
Broken polymer chains reform to repair a crack in this material when it is pressed together and exposed to UV light.
A new polymer material that can repeatedly heal itself at room temperature when exposed to ultraviolet light presents the tantalizing possibility of products that can repair themselves when damaged. Possibilities include self-healing medical implants, cars, or even airplane parts.
Self-healing concrete works because it can bend.
A concrete material developed at the University of Michigan can heal itself when it cracks. No human intervention is necessary–just water and carbon dioxide.
Cells in the retina of mice can be coaxed to create new neurons following an injury, according to new research from the University of Washington. This is the most definitive demonstration to date that such regeneration is possible, given the right cues, for a specific type of neuron in the inner retina of a mammal.
UV light illustrates how the epoxy resin bleeds into a fracture
You may have heard about about Greece’s self-healing house, now aerospace engineers at Bristol University have applied the concept to the development of self-repairing aircraft.
