Engineers invented a paper Bluetooth keyboard

US engineers invented interactive paper. It can be used as a keyboard. A new principle of printing, invented by specialists of the American Purdue University, allows making a Bluetooth keyboard directly on paper.

For this, it is covered with a layer of particles with high fluorine content. As a result of processing, the paper repels water, oil, dust, and it has zones that can support an autonomous Bluetooth connection. Power will be generated from contact with the user’s finger, so no external power supply is required.

Experts point out that the scopes of application of such paper can be multiple. In addition to gadgets, it can be a “smart” packaging. At the same time, the technology will be relatively inexpensive and accessible, and after some time any person will be able to print such a keyboard independently.
