Progress was made in donghua university wearable energy research and development

Donghua university, 21, said in a news release, the school professor hong-zhi wang group, the new progress in the field of wearable energy related research results in the amphibious energy yarn and the continuous and large-scale preparation of textile famous international academic journals published under the title, 'the natural & middot; Communication ( Nature Communications) 。

the team believes that fiber, yarn, fabric will become a new generation of power carrier. But mature power generation technology, such as photovoltaic, thermoelectric, piezoelectric/friction power, and the combination of clothing material and textile industry is a challenge. The energy performance of textiles to large-scale production, energy devices are susceptible to environmental humidity effect, and a lack of using single yarn for power generation technology. “ Energy throughout garment &; The development is still a long way to go.

in the challenge of 2017, after the entry of the vehicle suspension fails, causing Sunswift eliminated from the tournament. At present, the team prepares for the 2019 bridgestone world solar challenge, ready to use Violet racing with rivals.

with the rapid development of wearable electronic devices, people demand for wearable energy increased gradually. Due to the lack of flexibility, traditional battery are not stretching, difficult to weave and other limitations, flexible carry-on energy material and devices development received lots of attention. Current research of wearable power supply most shows & other; Wear & throughout; Energy in the form of the device, its main as clothing addition, still lack of wearing comfort. Clothing, by contrast, ontology is a ready-made physical carrier, is a more ideal wearable function integration platform.

in this work, the researchers using industrial-grade spinning equipment can be tensile friction generating yarn continuous and large-scale production, and further discusses the metal contact with amorphous polymer/separation of single electrode potential well model, first proposed the friction power generation device of electric potential/polarization coupling effect hypothesis. Coupled with special skin-core structure design and gain power mechanism, the work of generating yarn without the interaction with other objects can be spontaneous, and can be applied to different atmosphere environment even in the liquid.

researchers using industrial-grade sample loom will be generating yarn knitted elastic fabric of generating were obtained, it also has the ability of amphibious work. Generating yarn can also with other commercially available fibers such as nylon fiber, polyacrylonitrile fiber woven together, such as the water vapor permeability of textiles, comfort, power can be effective control. Researchers in power fabric made of & other; Energy throughout garment &; Shows that it is a electronic equipment lithium battery, drive wireless signal transmission system, such as capture human motion work

donghua university paper first completed units, donghua university institute of materials research Gong Wei river as the first author Dr Long schooling, Hou Chengyi associate professor, professor zhang researcher, hong-zhi wang to corresponding author. The research work has been the basic scientific research in colleges and universities were key projects of interdisciplinarity, lift engineering for young scientists of China Association for Science and Technology, donghua university motivational plan funded by such funds.

according to introducing, advanced functional materials group ( 先进功能材料集团AFMG) Belonging to donghua university institute of materials, the tutor team include: hong-zhi wang, professor yao-gang li, professor zhang, a researcher at Hou Chengyi deputy researcher. Group has been engaged in intelligent color/deformation, energy conversion and storage, sensor and catalytic functions such as materials, especially for the application of smart clothing, developed a series of the function of flexible wearable material and fiber devices.
