© 2018 Elsevier Ltd Pathogenic bacteria that give rise to infection have posed major health concerns over the past several decades. In this paper, we propose a self-powered active disinfection system controlled by human motions. The system is mainly composed of a multilayered triboelectric nanogenerator (m-TENG) for the harvesting of biomechanical energy and conductive fabrics as electrodes for the wearable disinfection system. The working principle of the system is based on hybrid effects of H 2 O 2 production and electroporation, which provide good disinfection performance toward gram-negative Escherichia coli (E. coli) and gram-positive Staphylococcus aureus (S. aureus). In addition, we also demonstrate that the presence of gold-coated tellurium nanowires (Au-Te NWs) on the fabrics increased the strength of local electric field and enhanced the system's disinfection performance. With the help of Au-Te NWs, the disinfection activities of the system reach values of more than 87% and 96% against S. aureus and E. coli, respectively, when the m-TENG was operated at a frequency of 1 Hz for 60 min. Furthermore, the disinfection activity can be strengthened by increasing the operation frequency or electric output of the m-TENG. Alternatively, the generated electricity can be stored in a capacitor to achieve rapid disinfection via an instantaneous discharging process. Because of the fiber-based structure in the disinfection device and the shoe-embedded design of the m-TENG, our proposed self-powered active disinfection system can be easily integrated into commercial textiles to fabricate smart clothes to combat pathogenic bacteria.
