Ambient Stable Triboelectric Nanogenerator Based on Conductive Filler Modified Silicone Rubber with Gas Barrier Encapsulation for Footstep Energy Conversion.

ABSTRACT: Human motion, particularly foot-ground interaction during locomotion, generates substantial biomechanical energy that remains largely underutilized. Triboelectric nanogenerators (TENGs) have emerged as a promising solution for harvesting such energy, yet their long-term performance under ambient humidity remains a major challenge for real-world deployment. Herein, a spring-assisted contact-separation mode TENG is reported, composed of high-temperature vulcanized (HTV) silicone rubber filled with 1 phr of conductive carbon black (600JD). The addition of 600JD increases the surface charge density by 55% compared to unfilled silicone rubber. The optimized device delivers a peak power density of 179.9 mW·m^-2 and is capable of powering over 1,900 commercial LEDs. To overcome moisture
