  We report the fabrication of electrically functional polyaniline thin-film
microdevices. Polyaniline films were printed in the solid phase by Laser
Induced Forward Transfer directly between Au electrodes on a Si/SiO2 substrate.
To apply solid-phase deposition, aniline was in situ polymerized on quartz
substrates. Laser deposition preserves the morphology of the films and delivers
sharp features with controllable dimensions. The electrical characteristics of
printed polyaniline present ohmic behavior, allowing for electroactive
applications. Results on gas sensing of ammonia are presented.
