Self-healing materials to repair iPhones and consumer culture

Self-healing materials have the potential to change our consumer culture in a significant way.

Many people have experienced the dread of dropping a smartphone only to pick it up and discover a scratched screen.

It is no surprise, then, that clumsy smartphone users everywhere rejoiced when Apple’s patent for self-healing iPhone displays was unveiled in February.

However, Apple is not the only company to develop self-healing technology. Natoco, a paint manufacturer from Japan, has developed a self-healing coating made from a polymer alloy that can be applied to different types of objects.

Natoco describes its coating through two different features. One is a “curling effect” that smoothes the surface of the object so that it is slippery, preventing scratches in the first place.

The second is a “trampoline effect”, a restorative feature that softens the impact on the dropped object and bounces back its energy, effectively “healing” the object.

The coating can be used for smartphones and other electronics that are easily scratched, but its applications are not limited to screens. Natoco foresees using it on vehicles, and it could also prove useful to prevent home appliances and kitchenware from being scratched.

Today, obsolescence is commonplace, and people discard objects that are still perfectly functional to replace them with the shiniest and newest models.

Smartphones are one of the most prominent examples of this throwaway mindset. If a phone gets a small scratch, it is often seen as unusable though it can still perform.

The quick cycle of buying and discarding is harmful for a number of reasons, particularly because it places no value on the resources that are used in the manufacturing of these items and ignores the resulting environmental impact.

Perhaps self-healing technology can transform our current attitude towards early obsolescence. Though not a perfect solution, people might be less likely to buy new electronics and appliances at such a speedy rate if coatings such as Natoco’s can maintain their sleek appearances by preventing and healing unsightly scratches.

By using products to their full capacity of functionality, we could reduce waste and save money.

As this technology continues to develop, we will find other applications for it as well. Self-healing coatings could strengthen a wide variety of structures and objects, from aircrafts to water pipes, increasing their safety as well as their aesthetic.

Maybe one day our homes could even withstand extreme weather damage with the help of these materials.

DJI’s First Drone Arena in Tokyo to Open This Saturday

Consumer drone giant DJI will open its first Japanese drone arena in the city of Tokyo this Saturday, providing a space for both hardened professionals and curious newcomers to hone their flying skills.

The arena, which covers an area of 535 square metres, will not only include a large flying area complete with obstacles, but also offer a store where visitors can purchase the latest DJI drones and a technical support area where drone owners can get help with quadcopter issues.

The hope is that the arena will allow those who are curious about the technology but currently lack the space to try it out to get involved.

“As interest around our aerial technology continues to grow, the DJI Arena concept is a new way for us to engage not just hobbyists but also those considering this technology for their work or just for the thrill of flying,” said Moon Tae-Hyun, DJI’s director of brand management and operations.

“Having the opportunity to get behind the remote controller and trying out the technology first hand can enrich the customer experience. When people understand how it works or how easy it is to fly, they will discover what this technology can do for them and see a whole new world of possibilities.”

In addition to its general sessions, which will allow members of the public to drop by and try their hand at flying drones, the arena will also offer private hire, including corporate events. For some companies, then, drone flying could become the new golf.

There will also be regular events, allowing pros to compete against one another, and drone training, in the form of DJI’s New Pilot Experience Program, for newcomers.

The arena has been launched in partnership with Japan Circuit, a developer of connected technologies, including drones.

“We are extremely excited to partner with DJI to launch the first DJI Arena in Japan,” said Tetsuhiro Sakai, CEO of Japan Circuit.

“Whether you are a skilled drone pilot or someone looking for their first drone, we welcome everyone to come and learn, experience it for themselves, and have fun. The new DJI Arena will not only serve as a gathering place for drone enthusiasts but also help us reach new customers and anyone interested in learning about this incredible technology.”

The arena is the second of its kind to be launched by DJI, with the first located in Yongin, South Korea, and detailed in the video above. .

Having opened in 2016, the area has attracted visitors from around the world, demonstrating serious demand for this type of entertainment space.

If the Tokyo launch goes well, it’s likely DJI will look at rolling out its arena concept to other cities, perhaps even bringing the model to the US and Europe.

For now, however, those who are interested can book time at the Tokyo arena here.

Commercial Human Spaceflight Advances Prompt Calls for Space Safety Institute

Commercial human spaceflight has been a long-held dream, but now it is finally poised to become a reality. Companies including Virgin Galactic and SpaceX are inching ever closer to taking private citizens into space, and there are serious plans for spaceports in several parts of the world, including Hawaii, the US, and Scotland, the UK.

But while the industry is advancing, the legal side of this fledgling commercial space industry remains underdeveloped, leading to calls for the development of an organisation to establish a framework for the safe operation of spaceports for human commercial spaceflights.

Writing in the journal New Space, Mclee Kerolle, from the United States International Institute of Space Law in Paris, France, has proposed the establishment of a Space Safety Institute recognised by the US congress and the United Nations.

This institute would “develop, enforce and adopt standards of excellence”, allowing the industry to develop while protecting it from liability and insurance risks.

“Currently, no international regulatory body exists to regulate the operation of spaceports,” he wrote. “This is unfortunate because while the advent of commercial human spaceflight industry is imminent, a majority of the focus from the legal community will be on regulating spaceflights and space access vehicles.

“However, the regulation of spaceports should be viewed in the same light as the rest of the commercial human spaceflight industry.”

The article focuses particularly on the establishment of a spaceport at the Kona International Airport in Keahole, Hawaii. At present, the spaceport’s development is subject to regulation by the Federal Aviation Authority, however there are aspects to spaceport development that do not apply to conventional aviation operations.

The institute would be designed to first and foremost ensure safety within the industry, so it would be important, according to Kerolle, to ensure it was made up of individuals with expertise in the field, rather than bureaucrats.

“To make sure that this flexibility is inherent in a Space Safety Institute, the organization should be composed of individuals within the industry as opposed to government officials who are not familiar with the commercial human spaceflight industry,” he wrote.

“As a result, this should protect the commercial human spaceflight industry to some liability exposure, as well as promote growth in the industry to ensure the industry’s survival.”
