Keyboards don’t exactly spring to mind when you think of high-tech innovations, especially now that we have voice and even gesture controls for our gadgets. Still, a new device out of the Georgia Institute of Technology is taking typing in a smart direction.
 
The Georgia Tech researchers have developed an intelligent keyboard that captures information about the force and length of keystrokes. They say these patterns are unique to different typists and could lead to a new type of biometric security, locking out anyone who doesn’t type like you do.
 
The keyboard can also power itself using something called contact electrification. It generates current when your fingertips touch the keys, which are coated with an electrode material. So we’re talking about a wireless keypad that never needs batteries.
 
The researchers published a paper about their intelligent keyboard in the journal ACS Nano. [Jun Chen et al, Personalized Keystroke Dynamics for Self-Powered Human–Machine Interfacing]
 
Maybe the best feature of the keyboard is that it’s basically made from layers of plastic and has no mechanical keys. That means you could drop crumbs or even spill coffee on it without any damage—forget voice recognition, now you’re talking!

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,

David M. Ewalt, Editor in Chief, Scientific American
