Migratory Animals‐Enlightened Hydrogen‐Bonded Organic Framework Nanorods Electrodeposited Nickel‐Based Fabrics for Ultrafast and Ultrasensitive Dual‐Environmental Magnetic Field Luminescence Responsive Monitoring Both in Air and Water

), ultrahigh measurement accuracy (relative standard deviation ≤ 0.52% and 0.097%), and great repeatability (900 and 540 cycles), respectively. Finite element simulation analysis of displacement and magnetic flux density changes for HOF-14@Ni fabric reveals that the magnetic response mechanism can be attributed to the magnetic-caused bending behavior resulting from magnetic attraction. Additionally, underwater magnetic wireless communication, motion perception, and air-underwater dual-environment magnetic intelligent real-time monitoring are further materialized. This work opens up a brand-new path for the application of luminescent (fluorescent) sensors in the field of dual-environment magnetic sensing.
