OECT Circuits

Printed Circuits

Organic electro-chemical Transitors (OECTs) allow for fast and simple manufacture by screen print on large-area polymer film. Low spread of transistor characteristics enables logic circuits, where resistors are made of the same PEDOT:PSS that is required for the OECTs. In this way, integrated circuits as NAND gates, flip-flops and 2-bit shift registers, that are already more complex and versatile than simple inverters, are printed on flexible polymer foil by our group.
