Swedish researchers have developed 'talking paper' that could be used to develop interactive packaging in the future.
The paper, produced from a combined effort by Mid Sweden University and packaging group SCA, plays pre-recorded messages in response to touch.
Project leader for media technology Mikael Gulliksson says: "We combine paper with printed graphic codes and electronically conductive ink that is engineered to be sensitive to pressure. Then digital information is embedded in the paper, and when it is touched, the information comes out via printed speakers."
Senior researcher Professor Hans-Erik Nilsson says the next step is to scale down the technology to enable it to be integrated into packaging, instructing consumers how to open the product, assist the blind, or even provide health warning on a pack of cigarettes.
Although the technology exists for use in billboards or interactive displays, the cost is prohibitive for use in most packaging.
"If it is high-cost packaging there are solutions – everything is related to cost. We can do it but to make it at a cost level that's acceptable for most producers is five years away," Nilsson says.
