Flexible Arc-Shaped Triboelectric Nanogenerator for All Directions and Highly Efficient Biomechanical Energy Harvesting and Human Motion Monitoring
Nano Energy(2024)
Abstract
As an environmentally friendly and renewable energy source, triboelectric nanogenerator (TENG) offers a fresh solution to the energy scarcity problem. However, the conventional three-dimensional (3D) TENG, which exhibits heavy angular dependence in energy harvesting, struggles to efficiently capture complex biological kinetic energy in practical applications. This study addresses this challenge by developing a novel flexible arc-shaped triboelectric nanogenerator (F-TENG). In comparison with traditional 3D flexible-based TENG, this generator notably minimizes the angular dependence on motion direction. Particularly for non-vertical mechanical energy harvesting, F-TENG can enhance collection efficiency by 35.5 %. Experimental results demonstrate that the open-circuit voltage and current of F-TENG textiles are 3 times and 2.6 times higher, respectively than those of conventional 3D flexible-based TENG. Its accuracy in detecting and identifying complex motions reaches 86.8 %, marking a 37.8 % improvement over traditional 3D-TENG. This study presents a promising perspective on the structural design of all directions and highly efficient biomechanical energy harvesting and its application in the field of intelligent sensing.
