Abstract:

Hydrogels are hydrophilic polymer networks prepared by physical or chemical cross-linking of gel molecules under optimal conditions. Due to their strong adjustable mechanical properties， self-healing ability， and good biocompatibility， hydrogels are considered to be a very promising sensor material for applications. In recent years， flexible wearable electronic devices have gradually become the main research direction in the field of human-computer interaction technology and artificial intelligence. Hydrogel sensors have been extensively studied because of their good performance and ability to monitor and transmit various signals， which promotes the flexible development of wearable electronic devices. This paper reviews the current research progress of electrodes for hydrogel-based sensors， firstly introduces the development history of hydrogel-based electrodes with different applications， then focuses on the application research of the electrode for hydrogel-based sensors in the field of flexible stretchable sensors， and finally summarises and analyzes the current shortcomings of the electrodes for hydrogel-based sensors， and the preparation process of hydrogel-based sensors and electrodes is prospected.
