Our paper on the realization of dispenser printed Bi-based magnetic field sensors is highlighted with a back cover page of Advanced Materials Technologies.

We present dispenser printing of magnetic field sensors based on commodity scale Bismuth powder. Benefiting from the non-saturating large magnetoresistance effect, this technology enables scalable large area printing of sensors with broad detection range on flexible and rigid substrates. Our technology could be applied for in-mold electronics, yielding shapeable custom-made sensors that can be geometrically adapted for lamination over uneven surfaces. Profiting from the high versatility in design and substrate material, we demonstrate magnetically controlled interactive devices based on a printed array of sensors, to be used for interactive advertisement, smart wallpapers, and security input panels.

This work is a result of fruitful cooperation between the Helmholtz-Zentrum Dresden-Rossendorf e.V. and Fraunhofer Institute IKTS in Dresden (group of Dr. Mykola Vinnichenko).
