LED-studded ‘electronic skin’ monitors your health, makes you look like a cyborg

In many ways, the future of healthcare will depend on “self care,” or patients caring for their own health using all technologies at their disposal. That might mean scouring the internet for nutrition facts about a meal, strapping a fitness tracker to your wrist before a jog, or reviewing a doctor’s recommendations based on a DNA test. Either way, people who take hold of their health will tend to live healthier lives.

Around the world, researchers are developing wearables to put power in patients’ hands and help them monitor physiological conditions, from heart rate to blood alcohol level.

Now, a team of engineers from the University of Tokyo has developed an ultrathin, breathable, and stretchable display that can be worn directly on the skin. This “electronic skin” display uses nanomesh electrodes to pick up on electrical signals from the heart, allowing it to monitor cardiovascular health and display data for the patient to view in real time via micro LEDs. The data can also be transferred wirelessly to a smartphone.

“Global aging is widely perceived as one of the most significant risks to global prosperity,” Takao Someya, an engineer and head of the University of Tokyo’s Someya Research Group, who developed the display, told Digital Trends. “In order to find the possible solutions to this pressing issue, home healthcare system in which people are responsible for their own health is getting more and more important. To build a home healthcare system, we need to foster age-friendly accessibility to information.”

Many of these wearable sensors are either relatively narrow in their ability to collect biometric data or else a bit bulky to wear, but the goal is to develop these wearable sensors to be broad in scope and practically unnoticeable to wear. The displays developed by the Someya Research Group fits into the “narrow but not bulky” category, in that it serves as an electrocardiogram but attaches unobtrusively to the skin.

“Our skin display can be nicely fitted on the skin due to its stretchability,” Someya said. “It exhibits simple graphics with motion including an electrocardiogram waveform measured with our skin sensors. It is the first stretchable display to achieve superior durability and stability in air. We have combined skin sensors with skin displays. Skin sensors realize comfortable, accurate, and safe data collections, [while] skin displays achieve natural, intuitive, and safe feedback.”

Moving forward, the researchers will work to refine the performance and reliability of their wearable, including increasing its resolution and aiming to make it full color. But, with these challenges complete, Someya sees devices like his ushering in more accessible and empowering healthcare.

“Skin electronics will enhance information accessibility for the elderly people or people with disabilities, who tend to have difficulty operating and obtaining data from existing devices,” he said. “The current aging society requires user-friendly wearable sensors for monitoring patient vitals in order to reduce the burden on patients and family members providing nursing care. Our system could serve as one of the long-awaited solutions to fulfill this need, which will ultimately lead to improving the quality of life.”

Someday presented his findings last week at the American Association for the Advancement of Science Annual Meeting in Austin, Texas.

The next big thing in science is already in your pocket

Supercomputers are an essential part of modern science. By crunching numbers and performing calculations that would take eons for us humans to complete by ourselves, they help us do things that would otherwise be impossible, like predicting hurricane flight paths, simulating nuclear disasters, or modeling how experimental drugs might effect human cells. But that computing power comes at a price -- literally. Supercomputer-dependent research is notoriously expensive. It's not uncommon for research institutions to pay upward of $1,000 for a single hour of supercomputer use, and sometimes more, depending on the hardware that's required.

But lately, rather than relying on big, expensive supercomputers, more and more scientists are turning to a different method for their number-crunching needs: distributed supercomputing. You've probably heard of this before. Instead of relying on a single, centralized computer to perform a given task, this crowdsourced style of computing draws computational power from a distributed network of volunteers, typically by running special software on home PCs or smartphones. Individually, these volunteer computers aren't particularly powerful, but if you string enough of them together, their collective power can easily eclipse that of any centralized supercomputer -- and often for a fraction of the cost.

Why AI will never rule the world

Call it the Skynet hypothesis, Artificial General Intelligence, or the advent of the Singularity -- for years, AI experts and non-experts alike have fretted (and, for a small group, celebrated) the idea that artificial intelligence may one day become smarter than humans.

According to the theory, advances in AI -- specifically of the machine learning type that's able to take on new information and rewrite its code accordingly -- will eventually catch up with the wetware of the biological brain. In this interpretation of events, every AI advance from Jeopardy-winning IBM machines to the massive AI language model GPT-3 is taking humanity one step closer to an existential threat. We're literally building our soon-to-be-sentient successors.

The best hurricane trackers for Android and iOS in 2022
Truck caught in gale force winds.

Hurricane season strikes fear into the hearts of those who live in its direct path, as well as distanced loved ones who worry for their safety. If you've ever sat up all night in a state of panic for a family member caught home alone in the middle of a destructive storm, dependent only on intermittent live TV reports for updates, a hurricane tracker app is a must-have tool. There are plenty of hurricane trackers that can help you prepare for these perilous events, monitor their progress while underway, and assist in recovery. We've gathered the best apps for following storms, predicting storm paths, and delivering on-the-ground advice for shelter and emergency services. Most are free to download and are ad-supported. Premium versions remove ads and add additional features.

You may lose power during a storm, so consider purchasing a portable power source,  just in case. We have a few handy suggestions for some of the best portable generators and power stations available.
