Nanotechnology promises to enable tiny, intricate circuits powering devices on any surface. But unless they’re harvesting energy from something like a heartbeat, the devices can only be as small as the smallest battery.
Now researchers at Rice University have combined the two, packing an entire lithium-ion battery into a single nanowire. The developers say it’s as small as such a device can possibly get.
Micro-supercapacitors could enable future geeks to go longer without recharging their smartphones or computers. Researchers have developed a way to build the energy-storing supercapacitors by using microfabrication methods similar to those which create microchips for electronic devices, according to ScienceDaily.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
