Shapeable magnetic sensorics — •Denys Makarov, Michael Melzer, Daniil Karnaushenko, Ingolf Mönch, Gungun Lin, and Oliver G. Schmidt — Institute for Integrative Nanosciences, IFW Dresden, 01069 Dresden, Germany

Magnetic sensor elements are usually fabricated on rigid wafer supports and provided as IC-chip packages with defined shape and size. In order to explore advanced application fields imposed by the novel trend of printable, flexible, and stretchable high-speed electronics [1], functional magnetic elements have to feature the same compliant mechanical properties. Magnetic nanomembranes have the potential to fulfill these demanding requirements of being reshapeable on demand after their preparation. We developed the technology platform allowing us to fabricate high-performance shapeable, namely, flexible [2,3], printable [4] and even stretchable [5] magnetic sensorics. These novel magnetoelectronics can be printed onto a variety of materials including regular paper [4], rolled up into a compact tubular architectures for applications in fluidics [3], as well as be stretched up to 270% without degrading in performance. These unique mechanical properties enable applications of the novel magnetic sensing devices in medical diagnostics and functional implants, safety and health care monitoring, e-mobility, flexible and low-cost consumer electronics, soft robotics as well as artificial skins.
