摘      要：Liquid metal(LM)exhibits a distinct combination of high electrical conductivity comparable to that of metals and exceptional deformability derived from its liquid state,thus it is considered a promising material for high-performance soft ***,rapid patterning LM to achieve a sensory system with high sensitivity remains a challenge,mainly attributed to the poor rheological property and ***,we report a rheological modification strategy of LM and strain redistribution mechanics to simultaneously simplify the scalable manufacturing process and significantly enhance the sensitivity of LM *** incorporating SiO_(2)particles into LM,the modulus,yield stress,and viscosity of the LM-SiO_(2)composite are drastically enhanced,enabling 3D printability on soft materials for stretchable *** sensors based on printed LM-SiO_(2)composite show excellent mechanical flexibility,robustness,strain,and pressure sensing *** sensors are integrated onto different locations of the human body for wearable ***,by integrating onto a tactile glove,the synergistic effect of strain and pressure sensing can decode the clenching posture and hitting strength in boxing *** assisted by a deeplearning algorithm,this tactile glove can achieve recognition of the technical execution of boxing punches,such as jab,swing,uppercut,and combination punches,with 90.5%*** integrated multifunctional sensory system can find wide applications in smart sport-training,intelligent soft robotics,and human-machine interfaces.
