Researchers at the Georgia Institute of Technology have invented an incredible smart keyboard that can identify users based on their unique typing patterns. As if that wasn't cool enough, the keyboard can also be powered by the static electricity generated by your keystrokes. Oh, and it's also waterproof and dirt-resistant.
The keyboard is equipped with technology that identifies users accurately based on their typing patterns and taking into account things like the amount of pressure applied to each key and the amount of time between keystrokes. The keys themselves are sheathed with a layer of special plastic that harvests finger-induced static charges to produce electricity.
Interestingly, the keyboard is made by inexpensive materials, which goes to show that innovation doesn't always have to be allied with expense.
