Wearable piezoresistive sensors based on three-dimensional graphene offer advantages such as simple preparation, low power consumption, and convenient signal acquisition, showing great potential in applications like human motion detection and health monitoring.
Three-dimensional (3D) graphene based wearable piezoresistive sensors are considered as promising flexible sensors due to their facile preparation, simple read-out mechanism, low power consumption and convenient signal acquisition. After nearly two decades of rapid development, 3D graphene based piezoresistive sensors have shown excellent application potential in human motion detection, heath monitoring, electronic skin, etc., which are envisioned as the critical technologies in future artificial intelligence system. In this review, the rapid development of 3D graphene based piezoresistive sensors are focused and analyzed. Various preparation methods of graphene and the complex fabrication process of multilevel 3D graphene structure are summarized, followed by the analyzing of different working mechanisms of 3D graphene-based piezoresistive sensors, which are illustrated by examples. The challenges and prospects of 3D graphene-based piezoresistive pressure sensors are discussed.
