Spintec has just completed the first prototype of its patented integrated 3D compass. This innovation stands to overturn the existing technology, which uses costly and difficult-to-assemble discrete components.
Spintec’s prototype uses a pyramid-shaped chip containing four magnetoresistive sensors, one on each side of the pyramid, to obtain the three components required for the local magnetic field. The sensors have the same sensitivity, resolution, and heat drift, making heat-drift compensation simpler.
Electronic compasses are increasingly found in everyday items like wristwatches, smartphones, and GPSs. Spintec’s technology reduces compass form factor, energy consumption, and cost, paving the way for a promising future.
