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 … [Read more...] about This device connects to your fingertips to produce energy while you sleep
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 … [Read more...] about MIT engineers invent human-like e-skin that could help monitor vitals
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 … [Read more...] about Gettin’ sweaty: Your wearable device may soon be powered by perspiration
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 … [Read more...] about This device stimulates nerves to help people with MS walk better
