摘要：

Triboelectric nanogenerators (TENGs) are a viable energy-harvesting technology that can harness kinetic energy from various environmental sources. TENGs primarily utilize linear and rotational motion as their kinetic energy sources. In the contact/separation mode, the primary mode of operation for linear motion, one cycle of AC output is generated with a single push. If the output can be sustained for an extended period from a single push, the potential applications for TENGs would significantly expand. In this study, we propose an innovative Linear-to-Rotary Conversion Triboelectric Nanogenerator (LRC-TENG), which incorporates a gear structure to convert linear motion into rotational motion and employs charge pumping to achieve efficient, prolonged output. The proposed TENG can sustain AC output for 3 s with a single push. This LRC-TENG is particularly well suited for applications such as stairways requiring safety lighting at night. Utilizing the LRC-TENG, when a person steps on a stair, it can illuminate the stairway for 3 s through more than 236 LEDs, ensuring safety during nighttime walking. This solution aids in guaranteeing pedestrian safety at night.
