  Since entering the information era, electronic devices gradually play an
important role in daily lives. However, the abuse of electronic devices leads
to corresponding electromagnetic EM wave pollution. The complex external
environment causes the potential for physical impact. In this work, an ANF
MXene SSG flexible sandwich structure was fabricated according to methods of
vacuum filtration, directional freeze-casting solidification, and polyurethane
encapsulation. Apart from its excellent protection function, the sandwich
structure also acts as a human body movement sensor.
