With an increase in the demand for smart wearable systems, artificial synapse arrays flexible neural networks have received considerable attention. A synaptic device with a two-terminal configuration is promising complex because of its ability to scale crossbar array architecture. To realize practical high density, it essential achieve reliable electrode lines that act as signal terminals. However, effective method develop intrinsically has not been developed. In this study, we achieved polymer using coffee ring-free micromolding capillaries (MIMIC). typical MIMIC, outward convective flow solution inherently deteriorates pattern fidelity. conducting (CP) lines, precisely controlled MIMIC by inducing Marangoni force. When and flows were balanced CP line patterns reliably produced The developed exhibited superior conductivity mechanical flexibility. Moreover, memristor consisting demonstrated potential realizing neuromorphic systems linked intelligence.
