Researchers at the VTT Technical Research Center of Finland say they have developed an electronic security tag that can be used to protect valuable shipments, and also say VTT's roll-to-roll technology for printing electronics can be used to manufacture them.
The security tags would enable logistics companies and retailers to determine whether products were tampered with during transportation.
The technology consists of a paper tag with an embedded battery and two colored light-emitting diodes. When a package is opened, the signal light will show whether it was opened earlier during transportation.
The roll-to-roll technology enables electronic circuits and sensors to be directly integrated into different materials. The researchers say the approach is cost-effective, suitable for mass production, and the tags are environmentally friendly.
"Our project partners have been examining the recyclability of the security element and its feasibility in logistics chains, so we now have a functional package in our hands," says VTT scientist Lisa Hakola. "In its studies, our project partner ITENE has detected that the components used in the security element have a very minor influence on the optical and mechanical properties of recycled fibers."
