Next, a layer of fluorinated ethylene propylene FEP is applied onto the ITO surface to serve as an electrification layer that generates triboelectric charges when touched by fingertips. While the self-powered feature could provide a convenience benefit and potentially eliminate the need for batteries in wireless keyboards, Wang believes the major impact of the device may be in helping to secure computers by using individual typing patterns or habits as a biometric.

Self-powered intelligent keyboard could provide a new layer of security

This will extend the RF sensor coverage of the Oplink system. The system is easy to install in a matter of minutes, and professional installation is never required. Categories Science and Technology. Jun Chen, et al. The intelligent keyboard records each letter intellignet, but also captures information about the amount of force applied to the key and the length of time between one keystroke and the next.

They’re available now, but before you order, be sure to read our review to find out the pros and cons of this product.

The device could provide a stronger layer of security for computer users. Researchers from the Georgia Institute of Technology as well as those from the Beijing Institute of Nanoenergy and Nanosystems and other labs in China have developed a keyboard that, among other capabilities, is able to identify users based on how they type.

The board is able to generate enough energy to power itself as well as small electronics at typing speeds greater than characters per minute.

Using signal analysis techniques, they were able to differentiate individual typing patterns with low error rates, Wang said. Best Offer Digital Display Screen. The Oplink system will instantly recognize and configure the new intellligent, and integrate it into your security system. Click image to enlarge. Recently commented stories Jump to forum mode.


Though eventually dissipating, the charges remain on the FEP surface for an extended period of time. Already have an account? It was sponsored by the U. No matter what Oplink system you own, you can easily expand it with any Oplink component by simply plugging it in.

This intelligent keyboard can determine who is typing on it and even generate its own electricity

When the finger moves away, the negative charges on the FEP side induces positive charges on the top electrode, and equal amounts of negative charges on the bottom electrode. As part of the study, his research group evaluated the keyboard under challenging conditions, including application of moisture, dirt and oil. Conventional keyboards record when a keystroke makes a mechanical contact, indicating the press of a specific key.

By analyzing such parameters as the force applied by key presses and the time interval between them, a new self-powered non-mechanical intelligent keyboard could provide a stronger layer of security for computer users. Aside from different types of key switchesbacklighting and perhaps macro capabilitieskeyboard technology has largely gone unchanged over the last several decades.
