Nanotechnology in Action: Organic Electronics

This activity focuses on the use of graphene in organic fibers, and their applications in organic electronics, e-textiles and wearable technologies. Students learn about the properties of graphene—a unique form of carbon—and how graphene-based fibers are fabricated, how to measure resistance, how to calculate resistivity, and how a material changes its electrical properties. Students also learn about the importance of defining design parameters, which is an important concept in the engineering design process. Students create graphite-based fibers using sodium alginate as the medium and a calcium coagulation bath, which is similar to the way in which graphene-based fibers are created in engineering research laboratories. Students then determine the factors that contribute to resistivity and vary these parameters to optimize fiber resistivity.
