Stretchable electromagnetic interference (EMI) shields with strain-insensitive EMI shielding and Joule heating performances are highly desirable to be integrated wearable electronics. To explore the possibility of applying geometric design in elastomeric liquid metal (LM) composites fully investigate influence LM geometry on stretchable heating, multifunctional wrinkle-structured LM/Ecoflex sandwich films excellent stretchability developed. The denser wrinkle enables not only better electrical conduction, higher effectiveness (SE) steady-state temperature, but also enhanced strain-stable far-field/near-field performance Joule-heating capability. More strikingly, compared most previously reported or electric heaters, densely wrinkled film could achieve multidirectional behavior slightly strain-enhanced strain-invariant SE under stretching parallel perpendicular field EM waves, as well show ideal over a larger strain range 250%. current findings suggest an effective strategy for developing LM-based properties.

Abstract Excessive electromagnetic pollution caused by waves can interfere with the normal use of electronic devices or cause unnecessary damage to human health. Although conductive polymer composites (CPCs) are used replace traditional metals as an effective strategy for managing undesirable waves, CPCs have a non‐negligible trade‐off in enhancement interference (EMI) shielding effectiveness and absorption coefficient because their reflection‐dominated EMI mechanism. Therefore, alleviate secondary pollution, absorption‐dominated asymmetric structures urgently needed. Recently, structural designs advanced significantly, but seldom been summarized discussed detail. Consequently, this review first systematically summarizes current progress after brief clarification about necessity configuration structure design. Afterward, various fiber, layered, porous, composite described. Besides, versatility is briefly introduced. Finally, challenges prospects proposed guide future advancement field.
