Published: July 11, 2024

Nowadays, the increasing electromagnetic waves generated by wearable devices are becoming an emerging issue for human health, so stretchable interference (EMI) shielding materials highly demanded. Elephant trunks capable of grabbing fragile vegetation and tearing trees thanks not only to their muscles but also folded skins. Inspired wrinkled skin elephant trunks, herein, we propose a winkled conductive film based on single-walled carbon nanotubes (SWCNTs) multifunctional EMI applications. The has sandwich structure, which was prepared coating SWCNTs both sides stretched elastic latex cylindrical substrate. shrinking-induced network could withstand up 200% tensile strain. Typically, when stretching direction is parallel polarization electric field, total effectiveness surprisingly increase from 38.4 52.7 dB at It mainly contributed increased connection SWCNTs. In addition, good Joule heating performance several voltages, releasing pains in injured joints. This unique property makes it possible strain-adjustable thermotherapy
