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.
