Abstract Myocardial infarction (MI) is a leading cause of mortality among cardiovascular diseases. Following MI, the damaged myocardium progressively being replaced by fibrous scar tissue, which exhibits poor electrical conductivity, ultimately resulting in arrhythmias and adverse cardiac remodeling. Due to their extracellular matrix‐like structure excellent biocompatibility, hydrogels are emerging as focal point tissue engineering. However, traditional lack necessary conductivity restore signal transmission infarcted regions. Imparting while also enhancing adhesive properties enables them adhere closely myocardial establish stable connections, facilitate synchronized contraction repair within area. This paper reviews strategies for constructing conductive hydrogels, focusing on application MI repair. Furthermore, challenges future directions developing discussed.

OECTs based 4Br-NDI-3EG exhibit low threshold voltage -0.022 V, which is lowest reported for channel materials to date. NDI-DTYA-3EG, π-expansion 4Br-NDI-3EG, maintains -0.041 V achieves 2 orders magnitude improvement electron mobility (1.04 × 10-2 cm2 V-1 s-1) owing its edge-on face-on orientation. Specifically, further NDI-DTYM-3EG attains sufficiently LUMO energy level (-4.51 eV), enabling spontaneous reduction 0.1 M NaCl solution without external bias, thereby self-doping. Consequently, it exhibits n-depletion-mode characteristics with transconductance value 287 μS. Moreover, devices made show exceptional stability, retaining 98% initial drain current after 150 min operation. These results provide insights into understanding conductor materials.
