"electron-beam exposure micropatterned high-density vertical, flexible, stable, fast redoxorganic electrochemical transistor arrays and circuits... electron beam lithography (eBL) produced pattern on p- and n-channel organic semiconductor films without employing masks or chemical solvents making them insulating but still able to conduct ions... transconductances 0.08–1.7 S, transient times <100 μs, stable switching properties >100K cycles... biosensors, wearable and neuromorphic systems"
