摘　　要：具有超高时间分辨率的事件相关电位(Event-related potentials,ERPs)技术为织物触觉舒适度的大脑感知表征研究提供了新的方法。在国内外文献基础上,归纳了ERPs技术在织物触觉舒适度感知表征中的研究进展,得到与织物轻微触感舒适度和接触压力舒适度感知相关的诱发电位成分分别为P50、P100、P200、P300和N450,并从物理、生理和心理3个方面探讨了将ERPs技术应用于织物舒适度感知过程中需注意的影响因素,为该技术与织物舒适度感知的深度结合提供应用基础。People’s health design requirements for the fit,functionality and comfort of wearable fabrics are gradually increasing,and the research on the perceptual mechanism of fabric tactile comfort is urgent.The event-related potentials(ERPs)technology with microsecond time resolution can quickly capture the changes of EEG signals related to fabric comfort,which is of great significance for exploring the dynamic perception mechanism of fabric comfort.ERPs technology can effectively monitor the relevant brain regions under the fabric contact stimulation in real time,so as to obtain the potential components related to the tactile comfort of the fabric.By recording the amplitude,latency and distribution of evoked potential components,we can quickly,objectively and accurately understand the psychological and physiological changes in the process of stimulation,so as to characterize the comfort level of human body.Specifically,the evoked potential components P50,P100,P200,P300 and N450 are characterization indexes of brain physiological response to mild tactile stimulation and contact pressure stimulation.In the process of application of ERPs technology,it is mainly affected by physical,physiological and psychological aspects.Physical factors include stimulation probability,stimulation frequency,stimulation mode,stimulation task difficulty and stimulus characteristics;physiological factors include age,gender,health status,sensory selection and stimulation site;psychological factors include subjects’emotional state and attention.At present,the evaluation of tactile comfort of fabrics based on ERPs technology has become a hot research topic.The amplitude and latency of its components can effectively evaluate the tactile comfort perception of fabrics,which provides great potential for in situ characterization of tactile stimuli of fabrics.Based on the brain perceptual representation principle of ERPs technology,we summarize the research status of ERPs technology in the evaluation of the fabric′s slight tactile comfort and c
