A Soft-Soft Contact Triboelectric Nanogenerator with a Ternary Four-Phase Structure for Self-Powered High-Efficiency Dust Removal on Mars.

ABSTRACT: Dust removal is essential for sustaining energy supplies in Mars exploration missions and base facilities. Existing devices typically depend on external power supplies, which may be inadequate in the harsh Martian environment. This paper proposes a novel wind-driven ternary four-phase soft-soft contact triboelectric nanogenerator (FPS-TENG) for dust removal. The device's double-stacked soft-soft contact structure outputs high-voltage electricity in four phases, generating a traveling wave electric field on the electrode surface. This field prompts dust particles to align with the wave's direction, enabling automatic dust removal without an external power supply. The FPS-TENG, as a ternary stacked soft-soft contact TENG, achieves output voltages that are 354% and 185% higher than those of c
