Experimental demonstration of the electrostatic induction and contact electrification for the ventilator-like of rotary nanogeneration

A fluorinated ethylene propylene (FEP) ring tube embedded in the bottom of ventilator to harvest additionally mechanical energy is introduced for hybrid inductive/triboelectric nanogenerator (H-TENG). First, charging glass bead moving closed to acrylic plane has distinctly identified for inductive polarities. Relationships between the moving speed on bead, charging bead amount and bead material with acrylic thickness have been thoroughly investigated. Results reveal that not only high moving speed but also bead charging and thin thickness enhance power output which possesses potential application for energy generation and self-powered sensor. Based on these results, the optimal H-TENG device combined with appropriate number of glass beads which conjuncts with three sets of electric brushes and heigh rotating speed enable to light up 121 LED lights. This study presents the inductive/triboelectricity mechanism of H-TENG by solid-dielectric base of rotating structure and inspires many imaginations of for harvesting large scale energy in the future.
