Wind energy and blue energy harvesting based on magnetic-assisted noncontact triboelectric nanogenerator

Triboelectric nanogenerator (TENG) as a promising approach has attracted extensive attentions from academic and industry. Herein, a novel strategy of wind and blue energy harvesting based on magnetic-assisted noncontact TENG has been demonstrated. Through the combination of magnetic responsive composite with TENG device, the wind and water forces could be converted into the contact-separation action between Al/Ni electrode and PDMS film. The influence of the relevant parameters (contact-separation frequency, wind speed and humidity, etc.) on the performances of the fabricated TENG has been systematically investigated. The results show the robust potential of magnetic-assisted noncontact TENG for wind and blue energy harvesting applications.
