Bioinspired Sensory Transduction for Magnetic Profile Recognition and Encryption

Advanced Materials, Volume 38, Issue 24, 27 April 2026.
Magnetic sensing in nature relies on dynamic transduction pathways, yet synthetic counterparts remain limited. We introduce a bioinspired system that couples electromagnetic induction in moldable magnetic soft composites with machine learning to encode and decode static (shape, rheology, magnetization) and dynamic (magnetization decay) magnetic ...
