High-tech labels with temperature memory for continuous monitoring of cold chains


The continuous monitoring of cold chains represents a major challenge for the chemical, pharmaceutical and food industry. Transient temperature peaks often occur during transport, which cannot be traced. And many of the systems used for temperature monitoring are expensive.

A new monitoring solution has now been developed by one of BAM’s research teams: plastic labels with a temperature memory.

"One has to imagine that the labels undergo a change in shape when heated to a temperature pre-selected by ourselves," explains Thorsten Pretsch, who heads the BAM project. "Two-dimensional codes contained in the labels change shape to such an extent that they become machine-readable and indicate that a temperature threshold has been exceeded."

Meanwhile, the scientists were able to show that labels equipped with Quick Response (QR) codes can be made machine-readable at 0 °C, 10 °C and 20 °C. If they are used to label temperature-critical goods, monitoring can be done by reading tests using a commercial smartphone. The temperature memory polymer tested in the experiments is a thermoplastic polyurethane and comes from Bayer MaterialScience AG.

Originally, the labels were developed for tamperproof labelling of goods. "The temperature memory opens up completely new possibilities that previously could not be implemented due to the high production effort," explains Pretsch.

The project is funded by the "Validation of the innovation potential of scientific research – VIP" initiative of the Federal Ministry of Education and Research (BMBF grant number 03V0043).

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
