Sweat sensor gets the goods without resorting to needles or workouts

If you don’t like getting needles or working out, this new medical wearable may be for you. It analyzes sweat instead of blood, and it doesn’t require patients to generate that sweat by performing strenuous exercises.Continue ReadingCategory: Medical, … Continue reading Sweat sensor gets the goods without resorting to needles or workouts

Water purification membrane generates electricity as it filters

A team from the Korea Institute of Science and Technology (KIST) and Myongji University, both located in Seoul, has published a new paper describing an “electricity generation and purification membrane for water recycling.”Continue ReadingCategory: Tec… Continue reading Water purification membrane generates electricity as it filters

Implanted generator could use ultrasound to charge pacemaker batteries

When a pacemaker’s battery gets low, the whole implant typically has to be surgically replaced. Scientists are therefore developing a noninvasive battery recharging system, which utilizes externally applied ultrasound.Continue ReadingCategory: Medical,… Continue reading Implanted generator could use ultrasound to charge pacemaker batteries

“Game-changing” anode exchange membrane promises cheaper green hydrogen

Electrolysis is a key component of the cost of green hydrogen, and a Korean team says it’s made a huge breakthrough with an anion exchange membrane that’s not only much cheaper than current proton exchange tech, but offers some 20 percent better perfor… Continue reading “Game-changing” anode exchange membrane promises cheaper green hydrogen

Lubricated coating could keep brain implants working longer

While brain-implanted electrodes do show promise for applications such as restoring capabilities to the disabled, they tend to lose their functionality over time. A new coating, however, could allow them to work much longer once implanted.Continue Read… Continue reading Lubricated coating could keep brain implants working longer

Linseed oil could find use in self-healing smartphone screens

Colorless polyimide (CPI) is a flexible, transparent alternative to glass, increasingly being utilized in bendable smartphone screens. It still can crack, however, which is why scientists have now developed a self-healing version of the material – and … Continue reading Linseed oil could find use in self-healing smartphone screens

Implantable gas sensor designed to dissolve when its job is done

While we have been hearing about the development of health-monitoring implantable sensors, most such devices would have to be surgically removed once no longer needed. An experimental new one, however, would just harmlessly dissolve.Continue ReadingCat… Continue reading Implantable gas sensor designed to dissolve when its job is done

Plant acid makes carbon fiber less flammable, more recyclable

Carbon fiber composite materials may be light and strong, but making them resistant to fire has been a bit of a challenge. Now, though, Korean scientists have discovered that a plant-derived substance both keeps them from burning and makes them easier … Continue reading Plant acid makes carbon fiber less flammable, more recyclable

Multi-function e-glasses track the brain, eyes and more

We’ve already seen electronic glasses that watch the wearer’s diet and automatically change focus, among other things. An experimental new pair monitors the user’s health, lets them control games, and switch to being sunglasses as needed.Continue Readi… Continue reading Multi-function e-glasses track the brain, eyes and more
