We developed a solvent-free chemical vapor deposition method to prepare high-quality films of the two-dimensional conjugated coordination polymer Cu-BHT (BHT = benzenehexanothiolate). The restricted metal ion mobility during the vapor–solid reaction enables high-resolution patterning via both bottom-up lithography, including the fabrication of micron-sized Hall bar and electrode patterns to accurately evaluate the conductivity and mobility values of the Cu-BHT films. Crystalline coordination polymers with high electrical conductivities and charge carrier mobilities might open new opportunities for electronic devices.

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.

Artificial magnetoception, i.e., electronically expanding human perception to detect magnetic fields, is a new and yet unexplored way for interacting with our surroundings. Here, we present skin-compliant touchless interactive devices based on spin-valves with out-of-plane sensitivity to magnetic fields. These devices reveal tunable logic characteristics, as needed for intuitive, energy efficient and insensitive to external magnetic disturbances magnetoreceptive human-machine interfaces.
