摘　　要：为实现瞬态捕捉织物刺激下的大脑反应,明确织物舒适度大脑感知机制,从织物舒适度感知过程以及事件相关电位技术的表征原理2个方面阐述事件相关电位技术在织物舒适度表征上的技术优势,并对国内外相关研究进展进行了综述,总结了与织物舒适度相关的诱发电位成分,得到与织物触觉感知存在相关的诱发电位主要为中期和晚期正成分以及刺激450 ms处出现的负电位成分。晚期正成分主要与织物表面粗糙度和接触压力刺激感知相关;中期正成分与刺痒感、接触冷暖感和黏体感相关;刺激450 ms处出现的负电位成分与大脑感知的抗干扰能力相关。与织物视觉舒适度感知相关的诱发电位主要为正电位成分、早期和中期负成分。强烈的织物视觉刺激会引起早期正成分、中期正成分和早期负成分振幅增大,但颜色组合数目增多会导致中期正成分和中期负成分的潜伏期延长,识别速度变慢。晚期正成分才是视觉舒适感知的最终决策成分。Significance A large number of experimental studies had been conducted on the relationship between the changes of various physiological indicators of the human body and the perception of human comfort under the tactile,visual and other perceptual stimulation of fabrics.Comfort evaluation based on physiological representations had made great progress and development.However,many methods still have defects in exploring the immediacy of fabric comfort characterization.With the continuous development of biological electroencephal technology,the relatively mature event-related potentials(ERPs)technique has shown the advantage of ultra-high time resolution in the brain perception study of fabric comfort.It was of great scientific significance to improve the temporal resolution of the detection technology to realize the instantaneous capture of dynamic information of brain sensory nerve and explore the in-situ sensing mechanism of fabric comfort.Progress From the perspective of the perceived process of fabric comfort,the perceived process of fabric comfort could be summarized as the process of physical,physiological and psychological interaction of the system of human body-fabric-environment.Although physical,physiological and psychological methods could all reflect the changes in the comfort level of the human body when it was stimulated by the fabric,it could be seen from the perceptual process that the formation of the comfort level originates from the cerebral cortex.Therefore,physiological representation technology based on brain perception obviously has more representational mechanism advantages for the study of human comfort level.From the perspective of the characterization principle of ERPs technology,ERPs potential signals were obtained by filtering,averaging and stacking electroencephalogram signals stimulated by the same event,and noise potential activities independent of stimulus would cancel each other out in the stacking process,so there was no nonlinear problem in ERPs signals.In addition,the technology
