Year: 2025
Type: article
Abstract: ABSTRACT Flexible tactile sensor is a new type of wearable device that mimics the sensory capabilities of human skin through flexible electronic technology and has broad application prospects in areas such as medical health monitoring, human-computer interaction, and robotics. In recent years, graphene and its derivatives have gradually become important materials for breaking through the performance bottlenecks of sensor due to their unique physical and chemical properties. This paper reviews the recent research of graphene-based flexible tactile sensor: (1) The material characteristics of graphene and its derivatives (GO, RGO) in sensor design; (2) Research of graphene-based flexible sensors based on piezoresistance, piezoelectricity, capacitance, and field effect transistor (FET); (3) The current research directions of graphene-based flexible sensors, including the development of composite materials, bionic structure design, AI-driven functional design, multimodal sensing and structural optimization. While previous reviews have detailed the material and mechanical aspects of graphene sensor, this review provides a unique perspective by focusing on the integration of Artificial Intelligence (AI) throughout the "material-structure-function" framework, revealing the role of AI algorithms in enhancing the sensitivity, stability, and functionality. Finally, this paper analyzes the current existing problems of graphene-based flexible tactile sensor and proposes a series of positive outlooks.
