We have fabricated a low-cost and flexible NH3 gas sensor using thermal ink-jet printing. The poly (3,4-ethylene dioxythiophene) doped with polystyrene sulfonated acid (PEDOT/PSS) with thickness of ~ 2 μm was used as a sensing film. The interdigitated electrode using patterned aluminum plate was attached over the sensing film. Atomic force microscopy results show the high homogeneous film and only small roughness is presented on the sensing film. This sensor exhibits high selectivity and sensitivity to NH3 at room temperature. The sensor response works linearly with gas concentrations between 100-1000 ppm. The modulation of conducting polymer/metal electrode interface plays a role in the sensing mechanism of NH3. Changes in the position of interdigitated electrodes can change the dominant sensing mechanism of typical polymer gas sensor.

AbstractPoly(vinylidene fluoride-trifluoroethylene) [P(VDF-TrFE)] copolymers are well known for their excellent ferroelectric and other related properties and they are being exploited as active components in many microdevices such as ferroelectric memory cells and infrared sensors. Compared with conventional photolithography, ink-jet printing provides a low-cost versatile method to fabricate polymer micro-devices. In this paper, the influences of driving waveform at the jet head, ink concentration, substrate chemistry, and the solvent quality on the printed P(VDF-TrFE) dots were investigated. It was found that well-defined P(VDF-TrFE) micro-dots with diameter of less than 30 mm and thickness of ∼1 μm can be printed by using a mixed solvent system, consisting of a good solvent with relatively low boiling temperature and a poor solvent with high boiling temperature, on perfluorinated hydrophobic gold surface. The printed P(VDF-TrFE) micro-dots possess crystallinity comparable to that of the bulk sample, suggesting that ink-jet printing technology is a promising micro-fabrication technology for manufacturing P(VDF-TrFE)-based micro-sensors and other micro-devices.

Conductive Thin Films

With the advantage of simplicity and low cost, ink jet printing has the potential to replace the traditional chemical and physical deposition technology in thin film fabrication. In this work, silver conductive thin films are deposited on glass and polyimide substrates by ink jet printing, where some major characteristics of the printed thin films are investigated and compared to those deposited by sputtering. The micro texture and residual stresses of the thin films are measured with X-ray diffractometry (XRD). Using thin film scratch tester, the adhesion of thin films deposited by both ink jet printing and sputtering is studied. Further observations on electric and optical performance by using visible wavelength photospectrometry, four-point probe, and surface profiler are also discussed. The result shows that the micro texture of the printed thin film behaves as good as the sputtered thin film. Furthermore, the micro scratch result illustrates that the adhesion of the printed thin film is even better than the sputtered thin film. It emphasizes that, after certain baking process, the ink jet printing has the possibility to replace sputtering in thin film deposition, especially for the polymer substrates.
