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 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). E. S. Oliveros Mata, C.

 | Our paper on the realization of flexible magnetoreceptors with tunable intrinsic logic for on-skin touchless human-machine interfaces is highlighted with a back cover page of Advanced Functional Materials. 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. This work is a result of a fruitful cooperation between the Helmholtz-Zentrum Dresden-Rossendorf e.V., Università Politecnica delle Marche (group of Prof. Gianni Barucca), Politecnico di Milano (group of Prof. Christian Rinaldi), University of Augsburg (group of Prof. Manfred Albrecht), and CNR Istituto di Struttura della Materia (group of Dr. Gaspare Varvaro).

 | Our paper on the realization of reconfigurable magnetic origami actuators with on-board sensing is highlighted with a cover page of Advanced Materials. We report on magnetic origami actuators equipped with highly flexible magnetic field sensors allowing to monitor the shape of the actuator and detect its magnetization state. The on-board magnetic field sensors enable feedback controls and guided assembly. These actuators are based on composite films of ferromagnetic microparticles embedded in shape-memory polymer films. Photothermal heating from light and applied magnetic fields enable on-demand reconfigurability. This work is a result of a fruitful cooperation between the Helmholtz-Zentrum Dresden-Rossendorf e.V., Elon University (Prof. Benjamin A. Evans) and North Carolina State University (group of Prof. Joseph B. Tracy). M. Ha, G. S. Cañón Bermúdez, J. A.-C. Liu, E. S. Oliveros Mata, B. A. Evans, J. B. Tracy, and D.
