Metal foams could provide lightweight radiation shielding

Radiation generally comes under the heading of "things you want to stay away from," so it's no surprise that radiation shielding is a high priority in many industries. However, current shielding is bulky and heavy, so a North Carolina State University team is developing a new lightweight shielding based on foam metals that can block X-rays, gamma rays, and neutron radiation, as well as withstanding high-energy impact collisions.Read More

Smart patch to take pain and hassle out of insulin injections

According to the International Diabetes Federation, 387 million people around the world suffer from diabetes, with this number expected to rise to 592 million by 2035. That adds up to a lot of blood sugar checks, diet watching and insulin shots, but researchers in the US have developed a patch that could revolutionize how the disease is managed. The patch contains of more than 100 microneedles, each automatically secreting insulin into the bloodstream when required.Read More

"Nano-accordion" conductors may find use in flexible and stretchable electronics

A new conductive, transparent, and stretchable nanomaterial that folds up like an accordion could one day be applied to the development of flexible electronics and wearable sensors, as well as stretchable displays. The researchers at North Carolina State University who created this "nano-accordion" structure caution that it is early days yet, but they hope to find ways to improve its conductivity and eventually scale it up for commercial or industrial use.Read More

Thin rubber membrane keeps a lid on cabin noise

In modern airliners, much of the structural paneling used in the cabin and wings has a honeycomb-like structure. Although this helps keep the weight down while maintaining strength, it does a poor job at blocking noise within the aircraft. That's why researchers from North Carolina State University and MIT have developed a membrane that helps the panels to do so. Read More

Unpowered ankle exoskeleton takes a load off calf muscles to improve walking efficiency

We might have started off in the water, but humans have evolved to be extremely efficient walkers, with a walk in the park being, well, a walk in the park. Human locomotion is so efficient that many wondered whether it was possible to reduce the energy cost of walking without the use of an external energy source. Now researchers at Carnegie Mellon and North Carolina State have provided an answer in the affirmative with the development of an unpowered ankle exoskeleton.Read More

Metamaterials allow ultrasound to penetrate bone and metal

Score another point for metamaterials. Researchers at North Carolina State University have designed complementary metamaterials that will aid medical professionals and engineers in diagnosing problems under the skin. These metamaterials are structured to account for so-called "aberrating layers" that block or distort the acoustic waves used in ultrasounds, making it possible to now conduct ultrasounds of a person's head or an airplane's wing – among other things.Read More

Sound-steered cyborg cockroaches could help save human lives

If you're ever trapped in a collapsed building and are calling for help, you might want to think twice before squashing any cockroaches that wander your way – one of them might have been sent to find you. Researchers from North Carolina State University are currently laying the groundwork for such a scenario, by getting cyborg-like "biobot" cockroaches to move towards sounds. Down the road, such insects may be used to locate victims at disaster sites. Read More
