“…The stripes are arranged such that the current flows through the NiFe layers are effectively orthogonal for adjacent arms of the Wheatstone bridge. This common technique has been extensively discussed in previous literature ( 64 , 65 ). The magnetic stripes are oriented orthogonally to the catheter axis, such that they roll up to form rings during the self-assembly ( Fig.…”

“…[124] There are many types of magnetic sensors in geomagnetic field detection: for example, superconducting quantum interference devices, which require extremely low operational temperatures of liquid nitrogen in order to attain great sensitivity. [125] Fluxgate sensors [126] based on exciting coil/high permeability core have been investigated for many years to detect DC magnetic and geomagnetic fields. This widely used fluxgate sensor is relatively cheap and temperature-independent; however, its magnetic hysteresis, offset value under zero magnetic field, and large demagnetization factor restrict design considerations.…”

In recent years, there is a meteoric rise in the prevalence of electronic wearables, and flexible wearables have attracted tremendous attention in human–machine interfaces due to their high biocompatibility, functionality, conformability, and low‐cost. Flexible magnetic smart skin is part of this rapidly progressing field of flexible wearable electronics, which has paved the way for a new path for human perceptual development, as they may form a new perception, also known as magnetic sense, that is, the capacity to detect and interact with magnetic fields. In this review, the concept of the magnetic smart skin is defined: magnetoelastomers and flexible magnetic sensors. In magnetoelastomers, different sources of magnetic field, structures, and applications are summarized by recent and renowned research. In flexible magnetic sensors, different flexible substrates, sensor types, and applications are also summarized. This review further concludes by discussing the outlook and current challenges of magnetic smart skin in human–machine interfaces.

“…For AMR sensors to detect the geomagnetic field, they must be geometrically conditioned to modify their intrinsic response, typically by using the barber pole method. [ 140–143 ] This method consists of stripes of ferromagnetic material, which are covered with slabs of a conductive material, oriented at 45° with respect to the long axis of the stripes. This modification forces the current to flow at 45° in the stripes, which effectively linearizes their AMR response around zero magnetic field.…”

Electronic skins (e‐skins) have established themselves as a versatile technology to restore or enhance human perception, and potentially enable softer robotics. So far, the focus has been mostly on reproducing the traditional functions associated with human skin, such as, temperature, pressure, and chemical detection. New developments have also introduced nonstandard sensing capabilities like magnetic field detection, to spawn the field of magnetosensitive e‐skins. Adding a supplementary information channel—an electronic sixth sense—allows humans to utilize the surrounding magnetic fields as stimuli for touchless interactions. Due to their vectorial nature, these stimuli can be used to track motion and orientation in 3D, opening the door to various kinds of gestural control for interactive devices. This approach to tracking provides an alternative or complement to optic‐based systems, which usually rely on cameras or infrared emitters, that cannot easily capture fine motion when objects are far from the source or the line‐of‐sight is obtruded. Here, the background, fabrication techniques, and recent advances of this field are reviewed; covering important aspects like: directional perception, geomagnetic field detection, on‐site conditioning, and multimodal approaches. The aim is to give the reader a general perspective and highlight some new avenues of research, toward artificial magnetoception.
