Stretchable strain sensors suffer the trade-off between sensitivity and linear sensing range. Developing with both high wide range remains a formidable challenge. Different from conventional methods that rely on structure design of nanomaterial or substrate, here heterogeneous-surface strategy for silver nanowires (AgNWs) MXene is proposed to construct hierarchical microcrack (HMC) sensor.
