Geometry Pattern for the Wire Organic Electrochemical Textile Transistor

Polyelectrolytes are promising materials as gate dielectrics in organic electrochemical transistor. On the other side, the fibre form transistor has become one of the most interesting topics in the field of smart textiles. The use of PEDOT:PSS to realize a parallel wire electrochemical textile transistor has been reported. A new geometry pattern makes the transistor easier to insert into textile fabric making the large-scale production possible. The length of transistor can be up to several centimeters. The On/Off ratio reached up to 10 3 . The switch time is near 15 s. An inverter circuit and a NOR-gated circuit have been realized by wire electrochemical transistors (WECTs). An amplifier was fabricated by using one transistor as well in order to demonstrate the feasibility of fully textile electronic circuits.
