摘      要：Stretchable electronics are crucial enablers for next-generation wearables intimately integrated into the human *** the primary compliant conductors used in these devices,metallic nanostructure/elastomer composites often struggle to form conformal contact with the textured *** electrodes have been consequently developed based on conductive nanocomposite and soft hydrogels to establish seamless skin-device ***,chemical modifications are typically needed for reliable bonding,which can alter their original *** overcome this limitation,this study presents a facile fabrication approach for mechanically interlocked nanocomposite/hydrogel hybrid *** this physical process,soft microfoams are thermally laminated on silver nanowire nanocomposites as a porous interface,which forms an interpenetrating network with the *** microfoam-enabled bonding strategy is generally compatible with various *** resulting interlocked hybrids have a 28-fold improved interfacial toughness compared to directly stacked *** electrodes achieve firm attachment to the skin and low contact impedance using tissue-adhesive *** have been successfully integrated into an epidermal sleeve to distinguish hand gestures by sensing mus-cle *** nanocomposite/hydrogel hybrids reported here offer a promising platform to combine the benefits of both materials for epidermal devices and systems.
