英文摘要	Recently, stretchable electronics have been highly desirable in the Internet of Things and electronic skins. Herein, an innovative and cost-efficient strategy is demonstrated to fabricate highly sensitive, stretchable, and conductive strain-sensing platforms inspired by the geometries of a spiders slit organ and a lobsters shell. The electrically conductive composites are fabricated via embedding the 3D percolation networks of fragmentized graphene sponges (FGS) in poly(styrene-block-butadiene-block-styrene) (SBS) matrix, followed by an iterative process of silver precursor absorption and reduction. The slit-and scale-like structures and hybrid conductive blocks of FGS and Ag nanoparticles (NPs) provide the obtained FGS-Ag-NP-embedded composites with superior electrical conductivity of 1521 S cm(-1), high break elongation of 680%, a wide sensing range of up to 120% strain, high sensitivity of approximate to 10(7) at a strain of 120%, fast response time of approximate to 20 ms, as well as excellent reliability and stability of 2000 cycles. This huge stretchability and sensitivity is attributed to the combination of high stretchability of SBS and the binary synergistic effects of designed FGS architectures and Ag NPs. Moreover, the FGS/SBS/Ag composites can be employed as wearable sensors to detect the modes of finger motions successfully, and patterned conductive interconnects for flexible arrays of light-emitting diodes.; National Natural Science Foundation of China [21601065, 51672110]; NSFC-Guangdong Jointed Funding [U1601202]; NSFC-Shenzhen Robot Jointed Funding [U1613215]; Guangdong Provincial Laboratory of Key Materials for High Density Electronic Packaging [2014B030301014]; SCI(E); ARTICLE; 28; 13
