MAG4INK – Design and manufacture of printed magnetic field sensors for flexible electronics

Magnetic field sensors are used to collect motion data such as displacements, rotations and vibrations. The sensors are currently manufactured on stiff substrates and have high masses and spatial expansions, which limit their use in many areas. In preliminary research, the project partners succeeded in producing magnetic field sensors on flexible substrates using a printing process. Besides low construction heights, these sensors also have a high sensitivity to small magnetic fields. The printing process also allows material savings to be achieved while maintaining flexibility in sensor design. The aim of the MAG4INK project is now to validate the large-volume, close-to-industry production of printed magnetic field sensors that exhibit high sensitivity. If successfully validated, due to their properties the sensors could also be used for medical applications and in smart fabrics for the first time.
