Magnetic field sensors are used to measure the position of machine parts and products with zero contact and zero wear – in a modern car, around 100 of such sensors are busy monitoring safety belt buckles and door locks, registering pedal positions, or are used for ABS, EPS, and engine control. They are cost-effective and robust, however, these conventional sensors generally measure only the magnitude of the magnetic field perpendicular to the chip surface. Good enough in many ways, magnetic field measurement remains imprecise and susceptible to interference. Michael Hackner, Dr.-Ing.
