The emerging applications of hydrogels in devices and machines require to maintain robustness under cyclic mechanical loads. Whereas have been made tough resist fracture a single cycle load, these toughened gels still suffer from fatigue multiple cycles reported threshold for synthetic is on the order 1 100 J/m2. We propose that designing anti-fatigue-fracture requires making crack encounter objects with energies per unit area much higher than fracturing layer polymer chains. demonstrate...
