摘要

This study aims to investigate the interaction between ultrafast laser beams and screen-printed silver (Ag) nanopaste films for strain sensors. After single pulse ablation of Ag nanopaste films with a thickness of 4.58 the ablation threshold was approximately 0.2 J/cm(2). By increasing single pulse laser fluences from 0.78 J/cm(2) to 1.87 J/cm(2), the laser-ablated line widths and depths of Ag nanopaste films were ranging from 22 +/- 0.1 mu m and 4 +/- 0.09 mu m to 44.8 +/- 1.4 mu m and 4.2 +/- 0.05 respectively. The sheet resistance of laser-processed Ag nanopaste films was measured by a four-point probe instrument. When the single pulse laser fluences set from 4.7 mJ/cm(2) to 1.97 J/cm(2), the measured sheet resistances near the laser-ablated line edge of 0.5 mm were 59.52 +/- 0.76 m Omega/sq and 115.83 +/- 6.11 m Omega/sq, respectively. The optimal ultrafast laser processing parameters consisting of the areal laser fluence of 47.4 J/cm(2), the laser pulse repetition rate of 300 kHz, the scanning speed of galvanometers of 500 mm/s, and the overlapping rate of laser spots of 96.1% were used to pattern strain sensors with transversal and longitudinal electrode structures on Ag film/glass substrates.
