Direct Transfer of Magnetic Sensor Devices to Elastomeric Supports for Stretchable Electronics

Stretchable electronics1, 2 is one of the most vital technological research fields of the latest years, aiming to revolutionize custom electronic systems toward being arbitrarily reshapeable on demand after their fabrication. This opens up novel application potentials for multifunctional high‐speed electronic systems like smart skins,3, 4 active medical implants,5, 6 soft robotics,7, 8 or stretchable consumer electronics.9, 10 A variety of functional components that can be subjected to high tensile deformations have already been introduced, including light emitting diodes,11 solar cells,10 pressure and temperature sensors,12 integrated circuitry,13 batteries,14, 15 antennas,16 and many more. Introducing stretchable highly sensitive magnetosensorics into the family of stretchable electronics17 was envisioned to equip this novel electronic platform with magnetic functionalities. This can be of particular interest for smart skin and biomedical applications promoted by very recent developments of imperceptible12 and transient6 electronics, as magnetoelectronic components can add a sense of orientation, displacement, and touchless interaction.
