Development and Application of Graphene Sensors in Human–Computer Interaction: A Review

Human-computer interaction (HCI) is the bridge between systems and people. In recent times, the advancement and implementation of HCI technology have necessitated the evolution of sensors towards enhanced flexibility, reduced weight, and smaller size. Graphene, as a rapidly progressing flexible material, exhibits outstanding mechanical, electrical, thermal, and other properties. When employed in strain, physiological and various sensor types, showing high quality of performance. Meanwhile, graphene sensors exhibit flexibility, biocompatibility, and cost-effectiveness, thereby addressing prevalent limitations in current HCI sensing systems. This paper aims to delve into the requirements of HCI sensing, with a primary focus on the cutting-edge research developments of graphene sensors in areas such as flexible wearable devices and real-time health monitoring. Additionally, it summarizes the significant contributions of graphene sensors in the HCI field. Furthermore, this paper explores the challenges that graphene sensors still encounter within HCI and propose the future development trends for these sensors.
