摘要

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 H2O2 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.
