This ultra light microbattery uses its own casing to store more energy
Improving the way current batteries store and deliver power is key to enabling faster charging and enhanced performance of electronic devices. However, the structural composition of most batteries today prevents the rapid transport of electrons and ions, limiting power density. Scientists have Read More...
This device connects to your fingertips to produce energy while you sleep
Earlier this year, we wrote about a breakthrough study from the University of Tokyo, where scientists invented a sustainable smart-watch battery that uses nothing but the wearer’s sweat to generate electricity. Following in the footsteps of that innovation, engineers at the University of Read More...
MIT engineers invent human-like e-skin that could help monitor vitals
Scientists at MIT have invented a health-monitoring device that not only mimics the stretchability and sensitivity of human skin but is also sweat-proof, a property that solves a major problem that has prevented previous versions from functioning properly. While different types of electronic skins Read More...
Gettin' sweaty: Your wearable device may soon be powered by perspiration
Wearable biosensors like smartwatches have become increasingly popular in recent years thanks to their great potential for monitoring people’s health. However, finding a suitable power source for these devices has proven challenging. On one hand, conventional button batteries are too bulky, while Read More...
This device stimulates nerves to help people with MS walk better
Many people who suffer from multiple sclerosis (MS) also have to deal with a condition called “foot drop.” Foot drop causes people to have difficulty lifting their feet or keeping their toes upward when they walk, which causes them to drag their toes and increases their risk of tripping. In Read More...
This wearable sensor can be printed directly onto the skin
Scientists at Penn State University have developed a wearable sensor that can be safely printed directly onto the skin to track things like temperature and blood oxygen levels. The printable sensor looks a bit like a high-tech henna tattoo and can be used to continuously record human data. Once the Read More...
Scientists create robotic fabric that could lead to therapeutic wearables.
A team at Harvard is creating therapeutic wearables using robotic fabrics. While robotic fabrics are far from new, they’re usually attached to bulky external machines that can modulate air pressure inside them to make them move or change their shape. Since that could limit their potential Read More...
This necklace can help detect high stroke risk before it’s too late
One of the major causes of stroke is unrecognized and untreated atrial fibrillation, an abnormal heart rhythm, that causes approximately 25 percent of all strokes. An ingenious new necklace, however, could make checking for it a quick and simple process. While it is the most common heart rhythm Read More...
