New technology uses radio to keep stock in order

07.03.2006


Research financiers Vinnova in Sweden and Tekes in Finland have granted SEK 6 million to a Nordic research project in printed electronics and RFID, Radio Frequency Identification. Eventually RFID will replace bar codes on packaging, for example. With the help of radio technology, many items can then be identified at the same time, which is of great value in taking inventory, for instance. The research project was initiated by a research team in RFID technology at Mid Sweden University.



The project, named ‘Printed RFID Sensor Solutions,’ is to develop tiny communicating RFID sensors. Unlike bar codes, RFID uses radio, which makes it possible to identify many items at the same time, in a store room, for example. RFID constitutes the base of a worldwide identification system called Electronic Product Code Network (EPC Network). Fully deployed, the system will be like a search engine such as Google, but not designed to find home pages but rather products and objects marked with RFID.

Even today products can tell us their identity all by themselves. But with the aid of new technology like the printed sensors to be developed in the project, packagings can provide much more information. Examples of such information are how the item was handled during transport, whether the packaging has been opened, and when and whether the good has been exposed to damaging temperatures or moisture.


“Our new sensor project will be a major contribution to the development of cheap and robust technology that can follow, track, and monitor individual products, from production to sale and finally to recycling,” says Professor Hans-Erik Nilsson, who is coordinating the project at the Section for Electronics at Mid Sweden University.

Printed electronics is based on ink and print dyes with electronic properties.

“New advances in nanotechnology are providing new possibilities for the rapid development of more efficient printing dyes,” says Hans-Erik Nilsson.

At Mid Sweden University this research got underway within the framework of the research program for the forestry industry at FSCN, Fiber Science and Communication Network, as early as 1999. Over the years the project has been developed in collaboration with both national and international companies.

The current project is being run in collaboration with the Royal Institute of Technology, Stockholm, Sweden, and VTT Technical Research Center in Finland.

Im Focus: UNH scientists help provide first-ever views of elusive energy explosion

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.

Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...

Im Focus: A Chip with Blood Vessels

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.

Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...

Im Focus: A Leap Into Quantum Technology

Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.

In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...

Im Focus: Penn engineers develop ultrathin, ultralight 'nanocardboard'

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure

Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
