The key element is the integrated temperature sensor, which provides important data about the condition of a product. The chip also boasts an impressive service life and robustness. Battery life is as long as three years; the sensor is watertight and resistant to X-rays as well as voltages of 18 kilovolts; and it can also withstand falls from a height of 1.5 meters without damage.
Blood is precious. According to the German Red Cross, roughly five million units of banked blood are needed in Germany each year, with 75 million units needed worldwide. There are generally fewer donors than recipients, which is why thorough documentation — and thus prevention of spoiled blood due to a break in the cooling chain or an exceeded expiration date — is so important. Unspoiled blood saves lives, and as much as €1 million a year can be saved by avoiding waste. The chips are now being successfully used at three Asklepios hospitals in Hamburg, Germany.
The biggest technical challenge is the need to protect the chip against the powerful forces at work in centrifuges, where it is subjected to as much as 5,000 G. The battery and the RFID chip survives undamaged in a specially developed housing. A micro-controller stores up to 30,000 measurements by the integrated temperature sensor and continuously plots the temperature curve.
DB Schenker, a global German logistics firm, and the world’s largest diagnostic company now also uses the clever chips to continuously monitor the temperature of sensitive air freight, such as medicines. On the chips is mounted a small green LED which shows the function of the data logger. If the temperature exceeds or falls below the predefined limit, the LED blinks multiple times in a row every six seconds as a warning. This enables the recipient to recognize that the contents may have been damaged immediately upon opening the package. To find out for certain, the recipient places the chip in a reader, which transfers the data to a computer. The system is GMP produced and qualified and can be delivered with a three year valid on-board calibration certificate.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
