In this study, a basic design of area-arrayed graphene nanoribbon (GNR) strain sensors was proposed to realize the next generation of strain sensors. To fabricate the area-arrayed GNRs, a top-down approach was employed, in which GNRs were cut out from a large graphene sheet using an electron beam lithography technique. GNRs with widths of 400 nm, 300 nm, 200 nm, and 50 nm were fabricated, and their current-voltage characteristics were evaluated. The current values of GNRs with widths of 200 nm and above increased linearly with increasing applied voltage, indicating that these GNRs were metallic conductors and a good ohmic junction was formed between graphene and the electrode. There were two types of GNRs with a width of 50 nm, one with a linear current–voltage relationship and the other with a nonlinear one. We evaluated the strain sensitivity of the 50 nm GNR exhibiting metallic conduction by applying a four-point bending test, and found that the gauge factor of this GNR was about 50. Thus, GNRs with a width of about 50 nm can be used to realize a highly sensitive strain sensor.

Flexible strain sensors with superior flexibility and high sensitivity are critical to artificial intelligence. And it is favorable to develop highly sensitive strain sensors with simple and cost effective method. Here, we have prepared carbon nanotubes enhanced thermal polyurethane nanocomposites with good mechanical and electrical properties for fabrication of highly sensitive strain sensors. The nanomaterials have been prepared through simple but effective solvent evaporation method, and the cheap polyurethane has been utilized as main raw materials. Only a small quantity of carbon nanotubes with mass content of 5% has been doped into polyurethane matrix with purpose of enhancing mechanical and electrical properties of the nanocomposites. As a result, the flexible nanocomposite films present highly sensitive resistance response under external strain stimulus. The strain sensors based on these flexible composite films deliver excellent sensitivity and conformality under mechanical conditions, and detect finger movements precisely under different bending angles.
