Abstract: Silver nanowire (Ag NW) is an interesting high performance conductive material. In this work, Polyol method is used to synthesize Ag NW and the final product is dispersed in isopropyl alcohol (IPA). The synthesized Ag NW was conducted at different cooking times at 1, 5, 10, 15, 30 and 60 minutes and different rate of dropwise precursor at 0.04, 0.07, 0.1, 1, 0.2 and 0.5 mL/min. The results show that the length of nanowires increased from 14 µm to 18 µm with diameter decreased from 97 nm to 89 nm. The fabrications of a strain sensor based on the silver nanowires composite with natural rubber are demonstrated by using different media of dispersion solutions which are IPA and silver extender along with a control experiment. Pre-vulcanized rubber latex is used as the substrate due to its good flexibility with high viscoelastic properties. The electrical and mechanical properties of strain sensors are shown in the form of gauge factor. The sample with silver nanowires dispersed in IPA composite with natural rubber show much larger gauge factor than the silver nanowire dispersed in silver extender. This is due to the cracking of Ag NW in IPA occur easier than Ag NW in silver extender during the electrical and mechanical measurement. The results show that the silver nanowire disperses in silver extender has high potential to for sensing a human health and human body motion detection in the future.
