A method of producing stretchable conductive nanofibers includes: providing stretchable nanofibers; providing a metal precursor solution by dissolving metal precursors in a solvent that may swell the stretchable nanofibers; bringing the stretchable nanofibers into contact with the metal precursor solution or its vapor for a sufficient time for the metal precursors to penetrate into the stretchable nanofibers; and reduce the metal precursors inside the stretchable nanofibers to metal nanoparticles.

Stretchable conductive nanofibers, stretchable electrode using the same and method of producing the stretchable conductive nanofibers

Provided is a thin film transistor on fiber and a method of manufacturing the same. The thin film transistor includes a fiber; a first electrode, a second electrode and a gate electrode formed on fiber; a channel formed between the first and second electrodes; an encapsulant encapsulating the fiber, the first, second, and gate electrodes, and an upper surface of the channel; and a gate insulating layer formed in a portion of the inner area of the encapsulant.
