A new type of very fast, low-power nanotube memory, developed by researchers led by Professor Eric Pop from the Electrical and Computer Engineering Department at the University of Illinois, may soon be commonplace in personal electronics like smartphones and laptops.
The nanotube memory uses just 1% of the energy required to power current flash memory, meaning a battery charge could last for weeks or months instead of hours or days! The low-power digital memory may even make battery-free electronics possible, since kinetic energy or energy from body heat could be enough to power devices fitted with nanotube memory modules. Not only are the carbon nanotubes used in the memory structures 10,000 times smaller than a human hair, they are incredibly stable and don't break down like metal wires do. On top of all of that, they won't be accidentally erased by a passing scanner or magnet.
