The sensors reveal up to 146% resistance change at 5 T at room temperature with a maximum resolution of 2.8 μT. It is validated experimentally that the peculiar quantum large orbital magnetoresistive effect remains effective in printed bismuth sensors, allowing their operation in high magnetic fields. The sensors are printed on different substrates including ceramics, paper, and polymer foils. Here, the authors report dispenser printing of a commodity scale nonmagnetic bismuth-based paste processed by large area laser sintering to obtain printed magnetoresistive sensors. As printed magnetoresistors rely on scarce or hard to manufacture magnetosensitive powders, their scalability and demonstration of printing with industry-grade technologies are the key material science challenges. Printed magnetic field sensors enable a new generation of human-machine interfaces and contactless switches for resource-efficient printed interactive electronics.
