In vitro cellular models with physical and chemical cues have several advantages in terms of defining experimental conditions and interpreting results compared with complicated in vivo models. Here, we present our recent research activities for developing solution-processable semiconductors, dielectrics, and conductors based on sol-gel metal oxide and organic electronic materials. With these materials, we fabricated all-solution-processable transparent high-performance thin film transistors (TFTs) and investigated the double-layer-capacitance mechanism supporting their stable underwater operation and extraordinary device performance showing the promising future application toward implantable neuro-electronics interfacing with neuronal cells or biological ionics. I will also briefly present our research progress in construction of artificial 3D neuronal networks or min-Brain and vertical silicon nanowire-based neuronal interfaces for the non-conventional neural engineering.
