Food waste is an enormous challenge, with implications for the environment, society, and economy. Every year around world, 1.3 billion tons of food are wasted or lost, waste-associated costs $2.6 trillion. Waste upcycling has been shown to mitigate these negative impacts. This study's optimized pomelo-peel biomass-derived porous material-based triboelectric nanogenerator (PP-TENG) had open circuit voltage 58 V a peak power density 254.8 mW/m2. As structures enable such devices respond sensitively external mechanical stimuli, we tested our PP-TENG's ability serve as self-powered sensor biomechanical motions. well successfully harvesting sufficient energy light-emitting diodes portable electronics, PP-TENGs monitored joint motions, neck movements, gait patterns, suggesting their strong potential use in healthcare monitoring physical rehabilitation, among other applications. such, present work opens up various new possibilities transforming prolific type into value-added products thus could enhance long-term sustainability while reducing waste.
