Power-generating fabrics that use human activity to generate energy have been around for several years. Now researchers at the Georgia Institute of Technology in the United States have gone a step further and developed a new fabric that can capture solar and wind energy at the same time. For the first time, the two power generation methods are integrated into one piece of fabric to help Yu has developed clothing that can charge mobile devices such as cell phones and navigation systems (GPS). The university’s official website announced the research results published in the magazine “Nature Energy” on the 13th.
The person who led the research was Wang Zhonglin (transliteration), a professor at the school of materials science and engineering at the school. He said that this hybrid electric fabric provides a new method. In the future, when you go out and the wind is sunny, you can easily add electronic products to the fabric. Charge.
The new fabric is woven with solar cells and electrostatic nanogenerator fibers made of ultra-light polymer fibers. The photoelectrodes are designed in the shape of wires and sewn into other fibers. The fabric can capture solar energy, and the nanogenerator fibers can rotate and slide. Mechanical motion energy such as vibration and vibration is converted into a small amount of electrical energy.
In the experiment, Wang Zhonglin’s team tied a piece of fabric the size of a piece of office printing paper to a small pole. When the car window was opened, the wind would blow the fabric and fly in the air like a colorful flag. The results show that when the weather is fine and the car is running, a 5 cm square piece of cloth can generate 2 volts of electricity in 1 minute. Even if the sky is covered with clouds, the fabric can generate enough electricity when the car is moving.
“This kind of fabric is very soft, breathable and light, and has a wide range of applications. It can be integrated into tents, curtains and wearable clothing.” Wang Zhonglin said, “The main material of the fabric is commonly used polymer materials, which are low-cost and lightweight. It is environmentally friendly and the production cost of the electrodes is also very low, so it is completely suitable for large-scale commercial production. “Their next step will be to test the charging life of the fabric and further improve its waterproof performance to ensure that it can be used normally in rainy days or humid environments.
