The old adage that good things come in small packages has never been truer -- and they can be smaller than a smartphone or a 7-in. tablet. A lot smaller.
And while some of the devices shown here are just tiny enough to be impressive, others can't even be seen with the human eye. Thanks to the latest advances in nanotechnology, items even in the microscopic world can have a huge impact on our lives.
From a diagnostic computer that can be implanted into the eye of a glaucoma patient to memory circuits made from only a dozen atoms, scientists have been doing a lot with a little. It all shows that the next big thing just might be very, very small.
