Researchers have developed the world’s thinnest and lightest magnetic sensor matrix sheet system that visualizes the two-dimensional distribution of magnetism on various surfaces.

The team has developed a thin and soft (“skin-like”) magnetic sensor matrix sheet system by integrating flexible electronic elements called organic transistors and giant magnetoresistive elements on a 1.5-μm-thick plastic film. This imperceptible circuit fabricated on a thin plastic film can be attached onto the skin of a person without causing discomfort and can function properly even when folded.

The magnetic sensor matrix sheet system, with a sensitivity 10 times higher than that of conventional systems, not only detects and amplifies weak magnetic signals, but also visualizes the two-dimensional distribution of magnetism in real time by automatically scanning magnetic sensor elements arranged in a matrix pattern.
