摘      要：Liquid metal represents a highly conductive and inherently deformable conductor for the development of stretchable *** widespread implementations of liquid metal towards functional sensors and circuits are currently hindered by the lack of a facile and scalable patterning *** this study,we report a fully solution-based process to generate patterned features of the liquid metal *** entire process is carried out under ambient conditions and is generally compatible with various elastomeric *** as-prepared liquid metal feature exhibits high resolution(100μm),excellent electrical conductivity(4.15×10^(4)S cm^(−1)),ultrahigh stretchability(1000%tensile strain),and mechanical *** practical suitability is demonstrated by the heterogeneous integration of light-emitting diode(LED)chips with liquid metal interconnects for a stretchable and wearable LED *** solution-based technique reported here is the enabler for the facile patterning of liquid metal features at low cost,which may find a broad range of applications in emerging fields of epidermal sensors,wearable heaters,advanced prosthetics,and soft robotics.
