Fraunhofer Institute for Electronic Nano SystemsThe researcher of Fraunhofer ENAS developed a new type of spintronic magnetic field sensor with two-dimensional vector resolution for contact-free measurement of distances, speeds, and angles. The magnetic field sensor's functionality is based on the physical giant magnetoresistance (GMR) effect. Technologies such as PVD and plasma etching processes are employed for fabrication. Thanks to those micro- and nanotechnologies used, it is possible to attain a very high signal-to-noise ratio, very short response times, a high degree of miniaturization, and a very low level of energy consumption. The GMR sensor is also bio-compatible. Conceivable applications range from the aerospace and the automobile industry to the very latest devices in medical engineering.
