For emerging wearable tech to advance, it needs improved power sources. Now researchers from Michigan State University have provided a potential solution via crumpled carbon nanotube forests, or CNT forests.

Changyong Cao, director of MSU’s Soft Machines and Electronics Laboratory, led a team of scientists in creating highly stretchable supercapacitors for powering wearable electronics...

In this time-lapse series of photos, progressing from top to bottom, a coating of sucrose (ordinary sugar) over a wire made of carbon nanotubes is lit at the left end, and burns from one end to the other. As it heats the wire, it drives a wave of electrons along with it, thus converting the heat into electricity. Credit: Courtesy of the researchers

The batteries that power smartphones,computers and electric cars, are mostly made of toxic materials such as lithium that can be difficult to dispose of and have limited global supplies. Now, researchers have come up with an alternative system for generating electricity, which harnesses heat and uses no metals or toxic materials.

The new approach is based on a discovery in 2010 by Prof Michael Strano in Chemical Engineering, MIT...

Presented in this work is a novel and facile approach to fabricate an elastic, attachable, and cost-efficient carbon nanotube (CNT)-based strain gauge which can be efficiently used as bodily motion sensors.

Body sensors, which were once restricted to doctors’ offices, have come a long way. They now allow any wearer to easily track heart rate, steps and sleep cycles around the clock. Soon, they could become even more versatile – with the help of chewing gum. Scientists report a unique sensing device made of gum and carbon nanotubes that can move with your most bendable parts and track your breathing.

Most conventional sensors today are very sensitive and detect the slightest movement, but many are made out of metal ie when twisted or pulled too much, they stop working...
