NOVELTY - A stretchable electrode ink composition comprises conductive nanomaterial, polymer material, and an ionic liquid. USE - Stretchable electrode ink composition used for forming electrode for thin film transistor for manufacturing stretchable inverter (all claimed), energy storage device, and wearable sensor lamp and flexible device. ADVANTAGE - The stretchable electrode ink composition produces stretchable electrode having small resistance change according to elongation and contraction. The thin film transistor and inverter has excellent device stability against stretching or flexible change, and is operated at a low operating voltage. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) manufacture of the stretchable electrode, which involves preparing an electrode ink by dissolving the stretchable electrode ink composition in a solvent, and printing the electrode ink on a substrate; (2) manufacture of thin film transistor, which involves printing the source electrode and drain electrode which is spaced apart from each other on a substrate using the electrode ink comprising the stretchable electrode ink composition, printing a semiconductor layer connecting the source electrode and drain electrode on the substrate using semiconductor ink, printing dielectric layer on the semiconductor layer using an ion gel ink, and printing gate electrode on the dielectric layer using conductive ink; and (3) manufacture of stretchable inverter, which involves preparing an inverter resistance ink by dissolving a multi-wall carbon nanotube, polymer material and ionic liquid in a solvent, forming an inverter resistor by printing the resistance ink on stretchable substrate, and electrically connecting the inverter resistor and thin film transistor.
