Abstract:

Hydrogel is a three-dimensional network structure gel composed of hydrophilic polymer chains， which can retain a large amount of water without dissolving after rapid swelling in water， showing similar characteristics to soft tissue. In recent years， with the popularity of wearable electronic products， electronic devices with flexible and stretchable properties are attracting more and more attention. As a composite hydrogel material with good electrical conductivity， conductive hydrogel can satisfy the above application requirements well. In this paper， the current research progress of conductive hydrogels was introduced， and the common preparation strategies of conductive hydrogels were summarized. We focused on the applications of conductive hydrogels in the field of flexible and stretchable sensors， and finally analyzed the shortcomings of conductive hydrogel-based sensors. With the rapid development of the Internet of Things （IOT）， smart terminals and 5G technology， the market demand for functional wearable electronic devices is growing day by day， and conductive hydrogels have broad application prospects in the field of flexible and stretchable sensors.
