Abstract The ongoing global energy crisis presents a significant challenge all over the world. In this study, triboelectric nanogenerator (TENG) made of recyclable thermoplastic polycarbonate has been proposed as promising environmentally friendly solution due to its potential capability convert low‐frequency mechanical sources such human motion and ocean waves into electricity with applications including powering wearable electronic devices self‐powered sensors. We introduce an antagonistically structured TENG ( A‐ TENG) composed honeycomb porous hc‐ PC) convex‐patterned dimethylsiloxane, employing novel one‐stage improved phase separation method. This A ‐TENG overcomes demerits others thanks high surface contact area, simplified fabrication process, enhanced conversion efficiency, cost‐effectiveness, requiring minimal investment. More importantly, work utilized hc ‐PC framework for slippery liquid‐infused (SLIPS) based owing special structure impregnate silicon oil within pore arrays mechanically support whole system. practical application SLIPS‐TENG was demonstrated while deployed on house rooftop harvest raindrop act rain detection sensor.
