摘　　要：The development of iontronic skin(I-skin)capable of ultrafast sensing in a wide pressure range,comparable to human skin,is of paramount importance for intelligent robotics.However,this remains a major challenge due to the lack of iontronic array architectures that can achieve ultrafast readout and crosstalk-free under large capacitance response generated within a wide pressure range.Here,we report a frequency-coding architecture of artificial ion mechanoreceptor skin(AIM-skin)that can provide a universal mode of iontronic array sensing and bypass the dependence of complex integrated back-end interface electronics.Notably,the successful implementation of orthogonal frequency coding in the AIM-skin with high sensitivity and ultrawide pressure range achieve ultrafast parallel readout for the spatiotemporal mechanical stimuli.Furthermore,the parallel zero-potential mechanism(PZPM)of the architecture effectively mitigates electrical crosstalk between sensing units.We have demonstrated that combhination of proposed device and deep learning has a broad application prospect in intelligent human-machine interaction and real-time dynamic robotic manipulation.
