Self-aligned, laser-cut organic electrochemical transistors in Flexible and Printed Electronics

Read our latest paper in Flexible and Printed Electronics by Reem Rashid, Robert Ciechowski and Jonathan Rivnay.

In this work we introduce a new method for OECT patterning which makes use of a hydrophobic insulation layer combined with a laser cutting method that provides self-alignment of source/drain contacts, insulation and channel, and allows for the active material to be "dragged and dropped" into laser cut OECT channels. We show that this method preserves the high performance of OECTs with good reproducibility across an array.
