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 realisation of printed recyclable magnetoelectronics is highlighted as back inside cover of Journal of Materials Chemistry A. We have developed printable magnetic field sensors with full recyclability. The printing technology streamlines the fabrication process, resulting in reduced energy consumption and equipment investments. Additionally, the circularity of materials at the end of the sensors' lifespan minimizes environmental footprint. With energy-efficient fabrication and material circularity minimizing environmental impact, our sensors hold significant promise for Internet of Things (IoT) applications requiring a multitude of low-cost sensors for real-time data exchange. This potential is exemplified by the integration of magnetic sensing in smart home systems.

 | 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.

 | 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.
