University of Helsinki (Finland) specialists invented technology for mass production of chips inserted into the paper.
This makes it possible to produce multi-purpose ’smart’ paper – such as print newspapers with front page news embedded video screens that would show clips, paper documents with embedded data they entered mini flash memory chips, or paper notes to electronic security means.
Finnish researchers have explored the so-called wise polymers – macromolecular compounds, whose properties change depending on changes in environmental conditions which produced copper nanoparticles which can be inserted directly into the paper.
They discovered that the copper particles down to about 8 nanometers, significant changes in their physical properties. This allows you to insert the paper through a mass of electronic components in the protective polymer.
After measuring the copper nano-structures embedded in paper the electrical conductivity the researchers found that in the paper quite a low temperature (15 – 200 degrees Fahrenheit) can be printed electrically conductive metal layers or objects.
According to the researchers this opens a new low-cost or even disposable electronics era.
