VTT Technical Research Centre of Finland has developed a new way of manufacturing a more accurate and smaller-sized electronic compass, which also consumes less power and is suitable for mass production. Possible applications include mobile phones, wrist computers and GPS navigator solutions.
VTT has developed micromechanic magnetometers that can be used in applications such as more sensitive electronic compasses integrated in mobile phones or other mobile devices. Integrated in a mobile phone, this compass can be used to locate, for example, the nearest ATM, pharmacy or doctor's clinic. In GPS navigator solutions, the compass supports the operation of other devices, for example in cases where the satellite connection fails as the result of buildings or trees. It can also provide directional information when the user is motionless.
For manufacturing magnetometers, VTT has developed a new processing method for silicon wafers. This enables the production of the sensors used for an electronic compass on one silicon chip instead of several chips. This means that the size of the compass can be smaller and the manufacturing costs for mass production can be lowered. Thanks to the reduced need for calibration, the compass is also more reliable than the existing electronic compasses. One of the benefits for the customer is that, owing to the reduced power consumption, the battery life of a wrist computer or a mobile phone, for example, is considerably longer when using the compass.
Commercial manufacturing of the component is expected to begin in Finland in a few year's time.
The research was funded by Tekes, and the cooperative partners included VTI Technologies Oy, Suunto Oy and Okmetic Oyj.
The research will continue with the new RESTLES project, focusing on streamlining the manufacturing process and making the sensors more compact.

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.
