Organic electrochemical transistors (OECTs) are one of the most promising device platforms for the field of bioelectronics. In comparison to other organic-based electronics, OECTs have several advantages including high transconductance, low voltage operation, and long-term stability. Here, we suggest an ultra-thin hybrid electrode was fabricated by thermally depositing ultra-thin sub-nano thickness Au electrode on crystalline poly(3,4 ethylene dioxythiophene): poly(styrene sulfonate) (PEDOT:PSS) thin film, which has a transmittance of 56% at visible range wavelength and low sheet resistance of 39.13 Ω/sq. Based on this structure, a semi-transparent and flexible top-contact structure OECT was fabricated that shows a transconductance of 2.5ms, and the performance was maintained even in the bending state(r=9mm). Finally, this semi-transparent OECT is attached to human skin to successfully perform electromyography (EMG) measurements. |
