A new way of manufacturing a more accurate and smaller-sized electronic compass for mass production by VTT

07.03.2007
Applications include consumer mobile phones, wrist computers and GPS navigation solutions

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.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
