Injectable hydrogels with conductivity are highly desirable as scaffolds for the engineering of various electrical stimuli-responsive tissues, including nerve, muscle, retina, and bone. However, oxygen deprivation within scaffolds can lead to failure by causing cell necrosis. Therefore, an oxygen release
