Exudate management and cell activity enhancement are vital to complicated wound healing. However, current exudate management dressings indiscriminately remove exudate, which is detrimental to cell activity enhancement. Herein, a novel class of electroactive bilayer (cMO/PVA) dressing is developed by constructing manganese oxide nanoneedle-clusters decorated commercial carbon cloth (MO), in situ casting polyvinyl alcohol (PVA) hydrogel, and finally charging. Benefitting from the hierarchical nanoneedle-cluster structure of MO, abundant active sites are sufficiently exposed to achieve high area-specific capacitances (e.g., 1881.3 mF cm
