a Structural illustration of the MIPM with the reconfigurable morphology iontronic mechanogate. The surface morphology can be programmed from flat to various structures, including microgrids, micropillars, and microtriangle. b The postsynaptic current (PSC) signals based on the MIPM with different surface structures under pressure stimulations. c Structural illustration of MIPM with the reconfigurable iontronic memristor. Through the control of multi-species ions as signal carriers, the MIPM exhibits programmable iontronic neuromorphics, resulting in multimode-reconfigurable processing of tactile signals. d, e The PSC decay curves and the absolute values of the change in PSC amplitude (ΔI), respectively, demonstrating the influence of different ionic compositions on the MIPM plasticity.
