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. The newly developed supercapacitor has demonstrated solid performance and stability, even when it is stretched to 800% of its original size for thousands of stretching/relaxing cycles.
The team’s results, published in the journal Advanced Energy Materials, may spur the development of new stretchable energy electronic systems, implantable biomedical devices, as well as smart packaging systems.
