Scientists develop self-powered smart keyboard that can identify the user too
A team of scientists have created a smart keyboard that will completely change the traditional way in which a keyboard is used for information input. The self-powered and self-cleaning intelligent keyboard powers itself by generating electricity when a user’s fingertips make contact with its multi-layer plastic materials. Besides that, the smart keyboard analyzes and record parameters such as force applied by key presses and the time interval between them, thus offering a stronger layer of security for the computer users. Passwords are the only way to protect our personal information on a computer, however they are themselves vulnerable to theft. That’s why the smart keyboard has been developed to offer more secure and user-friendly solution to safeguard the data on our computers.
Along with recording when a keystroke makes a mechanical contact indicating the press of a specific key just like conventional keyboards, the new self-powered keyboard also captures some additional information. It records data about the amount of force applied to the key and the length of time between one keystroke and the next one. As the typing style of every individual is unique, it can provide a new biometric for securing computers from unauthorized use.
Every punch of the keys produces a complex electrical signal, therefore the new keyboard could also generate enough electricity to charge a small portable electronic device or power a transmitter to make the keyboard wireless. The intelligent keyboard is made up of vertically-stacked transparent film materials and according to the developers will be competitive with existing keyboards, in both cost and durability.
The smart self-powered keyboard is developed by Zhong Lin Wang, a Regents professor in the School of Materials Science and Engineering at the Georgia Institute of Technology along with scientists from Beijing Institute of Nanoenergy and Nanosystems, Chongqing University and University of California, Riverside.
