Title:
ALL-LIQUID TRIBOELECTRIC NANOGENERATOR FOR HARVESTING DISTRIBUTED ENERGY
Document Type and Number:
WIPO Patent Application WO/2024/061278
Kind Code:
A1
Abstract:
The subject invention pertains to a comprehensive investigation of leading mechanisms of contact electrification in various liquid-liquid systems and an all-liquid TENG with optimized materials and structures to harvest energy from rainwater. Embodiments of the provided all-liquid TENG can generate a high charge density (e.g., 3.63 μC/L) with high output stability (e.g., crest factor≈1.1) and long effective contact electrification time. In certain embodiments, based on the direct current characteristics, energy harvested from rainwater can be fed directly to electronic devices and a self-powered rainfall sensor can also be implemented. Embodiments of the subject invention provide all-liquid systems useful in applications including distributed green energy, passive sensors, and other self-powered devices.
