Sweden: Successful production of said paper ... speaking!

Swedish scientists have successfully produced a paper board capable of producing sound every time you touch it. This invention opens many applications in advertising and business.

A Mid Sweden University research team has released a fourth generation of paper capable of interacting with computers according to a new technology: paper and digital integration. Dr. Mikael Gulliksson, research project leader, said: 'We combine paper with graphic circuits and conductive ink that is very sensitive to impact forces.'

Speaking to the press, Gulliksson said: 'When you get close to the board and place your hand on a certain position - such as a picture of a beach - you will immediately hear a short description of the beach. That sea came from the board '.

In fact, this board is a display with a built-in speaker and a digital paper with electronic components installed. This type of paper is able to interact with user impacts.

As a key factor for the operation of the board, the paper is printed with extremely sensitive conductive ink, and when impacted by a pressure, it will transfer information to a microcomputer that already contains audio file. Next, the sound will be emitted from the loudspeaker circuit, made up of layers of conductive ink above an empty small chamber to create a barrier.

This special paper is sandwiched between a thick, hard cover and another piece of paper on which the designs for the contents of the board are printed.

With this technology, the team released the first product as a showcase of tourist attractions. Dr. Gulliksson said: 'This pilot project can also be used for stores in stores as well as where information is needed to advertise.'

Currently, the display panel produced by this technology is quite expensive, so the team is trying to find ways to lower the price so that users can easily change the content and replace them as needed.

According to Gulliksson, the applicability of this project is huge. In the future, experts will study the reduction of this technology model to be used in many different areas.

Gulliksson said: 'Our next idea is to study the application of this technology in the production of goods packaging'. He stressed: 'It will be useful and interesting if it is used for cigarette packs. Then, instead of reading the warning about harmful effects of cigarettes, you will hear that content in a soft voice. '
