Abstract

The mechanism of the neuro-electrophysiological response of the human brain to skin tactile stimulation has always been an important research topic in the field of comfort perception of textile materials. In order to explore the characteristic neural potential components induced by various fabric tactile stimulation and their influence rules, event-related potential technology with ultra-high time resolution was introduced to monitor the somatosensory brain region under tactile stimulation of fabrics with different tactile properties, and the signal changes of related potentials were extracted and analyzed. The results showed that the amplitudes of N100 increased with the stiffness of the fabric, the amplitudes of P200 decreased with the smoothness of the fabric, and the amplitudes of P300 decreased with the smoothness and softness of the fabric. These results indicated that N100, P200, and P300 potentials could be used as neurophysiological response indexes of brain neurons to distinguish the subtle differences in fabric tactile properties. This finding not only laid a scientific theoretical basis for the brain perception mechanism of fabric tactile properties, but also provided a possibility for further quantification characterization of textile comfort perception.

利用事件相关电位法研究织物的触觉感知

人脑对皮肤触觉刺激的神经电生理反应机制一直是纺织材料舒适感领域的重要研究课题。为了探索各种织物触觉刺激诱发的特征神经电位成分及其影响规律，本文引入了超高时间分辨率的事件相关电位技术，监测不同触觉特性织物触觉刺激下的大脑躯体感觉区，并提取和分析了相关电位的信号变化。结果表明，N100 的振幅随织物的硬挺度而增加，P200 的振幅随织物的平滑度而减小，P300 的振幅随织物的平滑度和柔软度而减小。这些结果表明，N100、P200 和 P300 电位可作为大脑神经元的神经生理反应指标，用于区分织物触觉特性的细微差别。这一发现不仅为织物触觉特性的大脑感知机制奠定了科学理论基础，也为进一步量化纺织品舒适感知特性提供了可能。
