Abstract
Carbon materials, such as CB, CNTs, graphene and CFs, have excellent conductivity, mechanical properties and chemical stability, and have been fully developed and applied in the field of smart wearable devices, especially the resistance strain sensors prepared from carbon materials. Although various feasible configurations of carbon-based resistance strain sensors have been proposed, challenges regarding material design, preparation methods, and low practicality still exist. This paper reviews the latest research progress of carbon-based resistance strain sensors from the perspective of preparation methods, and discusses the mechanical properties, effective sensing tensile range, sensitivities, and different application scenarios, and provides suggestions and prospects for producing carbon-based resistance strain sensors. Finally, the future challenges and favorable development opportunities in the field of carbon-based resistance strain sensors are summarized.
