Shapeable Magnetic Sensorics
There is a trend in electronics towards becoming shapeable (flexible, stretchable or printable), which allows electronic components to be arbitrarily reshaped after fabrication. This unique feature offers new unexplored functionalities for the markets of consumer electronics and eMobility. Shapeable electronics and optoelectronics have been developed already for a few years.
Very recently, we added a new member to this family - the shapeable magnetic sensorics, which pave the way towards the development of a unique class of devices with important functionality being not only shapeable and fast, but also with the ability to react and respond to a magnetic field. Shapeable magnetic sensor devices could enable the fabrication of, e.g. health monitoring systems, where large-angle folding of the micrometer-sized functional elements is a crucial prerequisite for a successful implementation.
In the ERC project SMaRT we aim to develop shapeable magnetoelectronics to the industry-ready product and integrate these magnetic field sensorics into flexible large area multifunctional devices consisting of flexible batteries, communication modules and different types of sensing elements, e.g. environmental, chemical, temperature.

 | Our paper on the discovery of the nonlinear Hall effect in elementary Bi thin films is highlighted as a cover of Nature Electronics. We demonstrate that in the elemental (semi)metal bismuth, the room-temperature nonlinear Hall effect is generated by surface states that are characterized by a Berry curvature triple: a quantity governing a skew scattering effect that generates non-linear transverse currents. The strength of nonlinear Hall effect can be controlled on demand using an extrinsic classical shape effect: the geometric nonlinear Hall effect. We performed high harmonic generation experiments to show the potential of polycrystalline Bi thin films for optoelectronic applications in the terahertz (THz) spectral domain. This work is result of fruitful cooperation of the HZDR team with the group of Prof. Carmine Ortix (University of Salerno, Italy). P. Makushko, S. Kovalev, Y. Zabila, I. Ilyakov, A. Ponomaryov, A.

 | Our paper on the development of a modular droplet-based fluidics for the realization of large volume libraries of codes for Lab-On-Chip systems is highlighted as a back cover of the Advanced Sensor Research. We propose and validate a concept for a multiparametric library of multi-droplet codes in fluidics, where information is stored in different physical and chemical properties like concentration of magnetic content, droplet volume and ionic concentration. The concept allows coding of more than 1 million droplets using available lab scale fluidic equipment, which makes it relevant for large high-throughput screening assays in drug discovery. This work is result of fruitful cooperation with the group of Prof. Lior Klein (Bar-Ilan University, Israel) and Dr. Asaf Grosz (Ben-Gurion University of the Negev, Israel). J. Schütt, H. Nhalil, J.

 | Our paper on the development of a new method to prepare high-quality films of the two-dimensional conjugated coordination polymer Cu-BHT is highlighted with the front cover page of Journal of the American Chemical Society (JACS). 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. This work is a result of fruitful cooperation between the Helmholtz-Zentrum Dresden-Rossendorf e.V., Dresden University of Technology, Katholieke Universiteit Leuven and Deutsches Elektronen-Synchrotron DESY.
