Abstract:Flexible sensors can meet the daily needs across various industrial sectors and have attracted widespread attention. Environmentally friendly, high-strength, high-flexibility, and high-specific surface area make nanocellulose an ideal material for the fabrication of hydrogel flexible sensors. In this paper, we summarize the synthesis methods of hydrogel sensors and strategies to improve their performance, focusing on the application of nanocellulose hydrogels in flexible sensor applications, and introducing the response of nanocellulose hydrogel flexible sensors to external stimuli such as stress, strain, temperature, humidity, and target analytes. Finally, suggestions are provided to address the challenges and issues of nanocellulose hydrogels, and their application in flexible sensors is prospected.
