Fiber‐Embedded Electrolyte‐Gated Field‐Effect Transistors for e‐Textiles

Electrolyte-gate organic field-effect transistors embedded at the junction of textile microfibers are demonstrated. The fiber transistor operates below 1 V, and delivers large current densities. The transience of the organic thin-film transistor's current and the impedance spectroscopy measurements reveal that the channel is formed in two steps.
