#431862 Want Self-Healing Robots and Tires? ...

We all have scars, and each one tells a story. Tales of tomfoolery, tales of haphazardness, or in my case, tales of stupidity.
Whether the cause of your scar was a push-bike accident, a lack of concentration while cutting onions, or simply the byproduct of an active lifestyle, the experience was likely extremely painful and distressing. Not to mention the long and vexatious recovery period, stretching out for weeks and months after the actual event!
Cast your minds back to that time. How you longed for instant relief from your discomfort! How you longed to have your capabilities restored in an instant!
Well, materials that can heal themselves in an instant may not be far from becoming a reality—and a family of them known as elastomers holds the key.
“Elastomer” is essentially a big, fancy word for rubber. However, elastomers have one unique property—they are capable of returning to their original form after being vigorously stretched and deformed.
This unique property of elastomers has caught the eye of many scientists around the world, particularly those working in the field of robotics. The reason? Elastomer can be encouraged to return to its original shape, in many cases by simply applying heat. The implication of this is the quick and cost-effective repair of “wounds”—cuts, tears, and punctures to the soft, elastomer-based appendages of a robot’s exoskeleton.

Researchers from Vrije University in Brussels, Belgium have been toying with the technique, and with remarkable success. The team built a robotic hand with fingers made of a type of elastomer. They found that cuts and punctures were indeed able to repair themselves simply by applying heat to the affected area.
How long does the healing process take? In this instance, about a day. Now that’s a lot shorter than the weeks and months of recovery time we typically need for a flesh wound, during which we are unable to write, play the guitar, or do the dishes. If you consider the latter to be a bad thing…
However, it’s not the first time scientists have played around with elastomers and examined their self-healing properties. Another team of scientists, headed up by Cheng-Hui Li and Chao Wang, discovered another type of elastomer that exhibited autonomous self-healing properties. Just to help you picture this stuff, the material closely resembles animal muscle— strong, flexible, and elastic. With autogenetic restorative powers to boot.
Advancements in the world of self-healing elastomers, or rubbers, may also affect the lives of everyday motorists. Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a self-healing rubber material that could be used to make tires that repair their own punctures.
This time the mechanism of self-healing doesn’t involve heat. Rather, it is related to a physical phenomenon associated with the rubber’s unique structure. Normally, when a large enough stress is applied to a typical rubber, there is catastrophic failure at the focal point of that stress. The self-healing rubber the researchers created, on the other hand, distributes that same stress evenly over a network of “crazes”—which are like cracks connected by strands of fiber.
Here’s the interesting part. Not only does this unique physical characteristic of the rubber prevent catastrophic failure, it facilitates self-repair. According to Harvard researchers, when the stress is released, the material snaps back to its original form and the crazes heal.
This wonder material could be used in any number of rubber-based products.
Professor Jinrong Wu, of Sichuan University, China, and co-author of the study, happened to single out tires: “Imagine that we could use this material as one of the components to make a rubber tire… If you have a cut through the tire, this tire wouldn’t have to be replaced right away. Instead, it would self-heal while driving, enough to give you leeway to avoid dramatic damage,” said Wu.
So where to from here? Well, self-healing elastomers could have a number of different applications. According to the article published by Quartz, cited earlier, the material could be used on artificial limbs. Perhaps it will provide some measure of structural integrity without looking like a tattered mess after years of regular use.
Or perhaps a sort of elastomer-based hybrid skin is on the horizon. A skin in which wounds heal instantly. And recovery time, unlike your regular old human skin of yesteryear, is significantly slashed. Furthermore, this future skin might eliminate those little reminders we call scars.
For those with poor judgment skills, this spells an end to disquieting reminders of our own stupidity.

#428357 UV Disinfection robot

Tech-Link Healthcare Systems partners with Blue Ocean Robotics Introducing UV-Disinfection Robot
Singapore, 1 November 2016 – The rise of robots have steered Tech-Link Healthcare Systems, a design and integrator of healthcare automation systems to offer solutions beyond automated storage and material handling systems. With a vision of providing holistic solutions for healthcare organisations, Tech-Link extends its capabilities by offering UV disinfection robot solutions via a strategic partnership with Danish robotics company, Blue Ocean Robotics to battle against Hospital Acquired Infections (HAIs).Singapore’s labour intensive healthcare environment and the unknown impact of HAIs in the developed city-state had beckoned Tech-Link Healthcare Systems to offer solutions in the area of disinfection. We recognised the rise in demand for robots to collaborate with humans and have identified this need for customers. Introducing robotic technologies as part of our suite of solutions is the company’s mission to innovate the way healthcare organisations work and enhance their customers’ experience.Tech-Link’s partnership with Blue Ocean Robotics affirms both companies’ efforts in reaching out to new markets with technology and solutions to ease manpower crunch, deliver greater value and improve the quality of healthcare services. As an official sales partner, we bring together Blue Ocean Robotics’ expertise in automating disinfection procedures to promote safer, efficient and more productive work environment.
“Tech-Link looks forward to developing reliable healthcare solutions with hardware and latest technologies from Blue Ocean Robotics for our customers in Singapore and abroad.” said Director of Tech-Link Healthcare Systems, Tan Hock Seng. “Our similar beliefs in the Blue Ocean strategy synergise the collaboration to improve the quality of healthcare services through robotics.” he added.“We are very excited about our new sales partner Tech-Link Healthcare Systems, since it is of great importance for Blue Ocean Robotics to expand our sales of new technologies beyond Denmark’s borders. Blue Ocean Robotics focuses on creating new markets for robots. This includes both the development of new technologies and the creation of new markets for revolutionary robot solutions. We welcome Tech-Link Healthcare Systems with open arms and look forward to a fruitful collaboration in the years ahead.” said Claus Risager, Rune K. Larsen & John Erland Østergaard, Partners and Co-CEOs, Blue Ocean Robotics.
UV-Disinfection RobotThe UV-Disinfection Robot – also called UV-DR – is an autonomous disinfection robot for hospitals, production lines and pharmaceutical companies. The robot is used primarily in, but not limited to the cleaning cycle with the aim of reducing spread of HAIs, infectious diseases, viruses, bacteria and other types or harmful organic materials.UV-DR is a mobile robot that can drive autonomously while emitting concentrated UV-C light onto pre-defined infectious hotspots in patient rooms and other hospital environments, thus disinfecting and killing bacteria and virus on all exposed surfaces. An exposure time of ten minutes is estimated to kill up to 99% of bacteria such as Clostridium Difficile.
