AB  - Triboelectric nanogenerators (TENGs) have emerged as promising devices for converting mechanical energy intoelectrical energy through contact electrification and electrostatic induction. However, the generated energy,unlike instantaneous power, current and voltage, is rarely addressed in the vibrant research field of TENGs. Inthis study, we investigate Intrusion–Extrusion Triboelectric Nanogenerators (IE-TENGs) based on nanoporoussilicon monoliths and non-wetting liquids (i.e., water and a 1 mg/mL polyethylenimine solution), addressing theenergy generated during this process, conversion efficiency as well as the mechanism underlying the observedphenomena. Compared to powder-based IE-TENGs, the use of monolithic silicon structures enables more efficientand reproducible energy harvesting, with significant improvements in both instantaneous power density andenergy per cycle. We also analyzed the impact of compression rate and liquid properties on electrical output,showing that higher compression rates improve power generation, while modifying the liquid medium signifi-cantly improves conversion efficiency, reaching up to 9
