Enhanced On-Demand Antibacterial Platform Based on Triboelectric-Nanogenerator-Induced Electrical Stimulation of Cu₂S Substrates.

ABSTRACT: Triboelectric nanogenerators (TENGs) offer a sustainable, battery-free solution for wearable electronics by converting motion into energy. However, direct skin contact poses bacterial contamination risks, requiring advanced antibacterial strategies. This study developed an on-demand antibacterial platform based on TENG-induced electrical stimulation of Cu₂S substrates, benchmarked against Cu₂O. Submicron-structured Cu₂S layers were fabricated via a novel sulfurization method applied to electrodeposited Cu₂O layers on fluorine-doped tin oxide (FTO) substrates. The resulting Cu₂S and Cu₂O thin films were integrated into a single-electrode TENG system, and their antibacterial efficacy was evaluated under electrical stimulation
