Small size electronic compasses

A new way of manufacturing more accurate and smaller-sized electronic compasses was introduce recently. This way consumes less power and is suitable for mass production. Applications include consumer mobile phones, wrist computers and GPS navigation systems.
Micromechanic magnetometers 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. For manufacturing magnetometers, VTT has developed a new processing method for silicon wafers. The size of the compass can be smaller and the manufacturing costs for mass production can be lowered.
Commercial manufacturing of the component is expected to begin in Finland in a few years time.
