2021/03/31
Recently, the team of Qu Lijun and Tian Mingwei, from Research Center for Intelligent Wearable Technology of Qingdao University, published an academic paper on smart electronic textiles entitled "Flexible All-textile Dual Tactile-tension Sensors for Monitoring Athletic Motion During Taekwondo" in Nano Energy, a TOP journal of advanced materials (Impact Factor 16.602). Through interdisciplinary cooperation among Qingdao University, Huazhong University of Science and Technology and Shenzhen University, this paper is co-authored by Ma Yulong, a postgraduate student from Research Center for Intelligent Wearable Technology and College of Textile & Clothing, and Ouyang Jingyu from Huazhong University of Science and Technology; Prof. Tian Mingwei, Prof. Qu Lijun and Prof. Tao Guangming from Huazhong University of Science and Technology are the co-corresponding authors.

In vigorous sports such as martial arts and fight, athletes will manage various movements and be hit by external forces, and the study of the inherent relation between multi-scale human space motion and force is the key issue to correct the sports form scientifically. At present, most of the electronic textiles used for sports monitoring only integrate discrete sensors with single function to analyze the change of body movement or external force. 

 

In order to solve the problem that it is difficult for smart fabric to perceive multiple signals synchronously, this paper proposes a textile structure design strategy to study a kind of dual perception smart textile. With the traditional process of textile core yarn and machine-made textile, the integrated dual perception smart fabric can monitor the tactile and tension stimulation in real time according to the principles of piezoresistance and capacitance. The integrated system has good sensing response to wide-range deformation (about 90% detection range) and thump (up to about 110 kPa), durability (about 100,000 tensile and compression cycles), moisture permeability and air permeability. The smart fabric proposed in this work can monitor dual tactile and tension movements in real time, which has great potential in the field of wearable sports.

 

In the past two years, Research Center for Intelligent Wearable Technology of Qingdao University has carried out fruitful work on smart textiles, and published 4 papers with Impact Factor greater than 10 (Nano Letters, 2019, 199: 6592-6599, ACS Nano 2020, 14: 559, Nano Energy, 2020, 76:104926, Nano Energy, 2021, doi.org/10.1016/j.nanoen.2021.105941), and 2 highly cited papers, which effectively boosted the textile subject development and enhanced the scientific research level and academic influence of textile interdisciplinary.
