A synergistically designed strain-insensitive conductive hydrogel with humidity-adaptivity supporting sustained functional durability

the incorporation of conductive additives. Cyclic tensile strain (10 000 cycles), prolonged exposure under fluctuated humidity conditions over 6 months (20%-50% fluctuated relative humidity), and low-temperature storage (-56 °C) were conducted to verify the sustained functional maintenance. The conductive hydrogel was practically qualified as a conductive interconnect for power supply and signal transmission. The results unfold a promising prospect of the conductive hydrogel with long-term reliability as a conductive interconnect.
