There's a new design concept out there for flash drives the thickness of a sticky note. The company, called dataSTICKIES, uses a relative newcomer material called graphene and a proprietary wireless data transfer protocol to get achieve this wafer-thin thickness.
Now, graphene is my favorite new material; I've been waiting for close to 10 years for someone to come out with a viable commercial application, and this is a pretty cool proto-product. Graphene is a form of crystalline carbon (essentially atom-think graphite) that is super strong and an excellent conductor. Research using graphene has taken place anywhere from medicine to energy to quantum science.
The dataSTICKIES company is using graphene to store data. Because graphene is an atom thick, the hard drive becomes a flat sheet. Instead of using USB to transfer the data, the company developed an optical data transfer surface to take advantage of the super thin material. This also makes transferring data easier since you no longer have to deal with the USB superposition effect (i.e., it takes at least three tries to connect the USB cable) or moving computers around to get to the USB ports.
Another cool thing with the dataSTICKIES is that it looks like you can increase the data capacity by stacking stickies. I'm not sure how that's supposed to work though, since you are supposed to be able to stack stickies as discrete drives.
These would be pretty awesome anywhere, but especially for people on restricted networks. Need to install some more pollers or every SolarWinds product you bought? Just slap a sticky on the computer.
