Recent Progress in Mechanically Robust and Conductive‐Hydrogel‐Based Sensors

Flexible electronic technology has developed rapidly in recent years, showing broad application prospects motion monitoring, wearable devices, and personalized medicine. Consequently, the demand for high sensitivity wide sensing range gradually increased. Conductive hydrogels have flexibility, excellent conductivity, good biocompatibility, making them ideal candidates fabricating flexible sensors. However, conductive exhibit weak mechanical stability, which limits their applications. Therefore, sufficient properties fatigue resistance are usually needed to fulfill requirements. Herein, research frontiers of sensors based on mechanically robust reviewed. While published papers always focus configuration design improvement performance, network effects performance limited. It is attempted this review fill gap by focusing principles enhanced applications devices. hydrogels’ structural designs, toughening mechanisms, properties, discussed. The different working mechanisms composed tough also Finally, future development directions challenges field highlighted.
