In a groundbreaking study, researchers have unveiled a novel liquid–solid triboelectric nanogenerator (LS-TENG) that harnesses the kinetic energy of water droplets, promising significant advancements in energy harvesting technology. Led by Lin Luo from the Center on Nanoenergy Research at Guangxi University, this innovative device employs inflatable columnar structures equipped with dual electrodes, allowing it to capture energy from both internal droplet motion and external droplet impacts. This dual functionality positions the LS-TENG as a versatile solution for sustainable energy generation, particularly relevant to the construction sector.
The construction industry has long sought efficient, renewable energy sources to power operations and reduce carbon footprints. Luo emphasized the potential impact of this technology, stating, “Our design not only optimizes energy harvesting but also opens avenues for integrating clean energy solutions in construction applications.” The LS-TENG can achieve a remarkable mass power density of 9.02 W·Kg ^−1 and an energy conversion efficiency of 10.358% from internal droplet motion, while the external component can generate over 140 V from a single droplet, with an impressive energy conversion efficiency of 22.058%.
The implications of this research extend beyond theoretical applications. With the ability to harvest energy from natural water sources, construction sites could utilize this technology to power tools, sensors, and other equipment, thereby decreasing reliance on traditional energy grids. Furthermore, the inflatable nature of the columnar structure means that it can be easily transported and deployed in various environments, making it an attractive option for remote or temporary construction projects.
Luo’s team has envisioned potential applications that include TENG aeration rollers, inflatable life jackets, and even energy harvesting tents and greenhouses. “The adaptability of our design means it can be tailored to meet the specific needs of different construction scenarios,” Luo added, highlighting the technology’s flexibility.
Published in the *International Journal of Extreme Manufacturing*, this research marks a significant step towards integrating advanced energy harvesting solutions into everyday construction practices. As the industry increasingly prioritizes sustainability, innovations like the LS-TENG could play a crucial role in redefining how energy is generated and utilized on construction sites.
