Abstract

Herein, we investigate the effects of 3D printed electrodes on electrophysiological signals and identify the important design elements required for manufacturing better electrodes for high body adhesion for smart wear. Ten electrodes of different shapes (plain, check, stripe, circular, radial cut-out) and thicknesses (0.5 mm and 1.0 mm) were manufactured. The electrodes were evaluated by testing on 20 healthy individuals (10 men and 10 women). To measure the electroencephalogram (EEG) of the participants, we used BIOS-S8 (BioBrain Inc., Korea), an 8-channel polygraph for multibody signal measurement. Data were analyzed using the SPSS 26.0 statistical program. The EEG values were significantly activated according to gender. For the male participants, relative alpha (RA), relative slow theta (RST), relative mid theta (RMT), and the ratio of SMR-mid beta to theta (RSMT) values were highly activated and for the female participants, RA, relative fast alpha (RFA), and relative slow theta (RSA) values were highly activated. There were no significant gendifferences in the EEG of both genders for the 10 types of electrodes. However, for the female participants, the ‘RA’ indices showed a significant difference based on electrode shape on the right temporal lobe (T4), but there was no significant difference based on the thickness. There was a significant difference in the subjective preference of the electrodes also. In the subjective evaluation, it was found that the differences based on the shape and thickness of the electrodes were sensitively recognized.

开发和打印用于智能穿戴设备高人体附着力的三维电极
在此,我们研究了三维打印电极对电生理信号的影响,并确定了制造更好的电极所需的重要设计元素,以实现智能穿戴设备的高人体粘附性。我们制造了 10 个不同形状(普通、方格、条纹、圆形、径向切口)和厚度(0.5 毫米和 1.0 毫米)的电极。通过对 20 名健康人(10 名男性和 10 名女性)进行测试,对电极进行了评估。为了测量参与者的脑电图(EEG),我们使用了 BIOS-S8(BioBrain Inc.数据使用 SPSS 26.0 统计程序进行分析。不同性别的脑电图值有明显差异。男性参与者的相对α(RA)、相对慢θ(RST)、相对中θ(RMT)和 SMR-中β与θ的比率(RSMT)值高度激活,而女性参与者的RA、相对快α(RFA)和相对慢θ(RSA)值高度激活。在 10 种电极中,男女参与者的脑电图没有明显的性别差异。然而,对于女性参与者来说,"RA "指数显示出基于右颞叶(T4)电极形状的显著差异,但基于厚度的差异并不显著。电极的主观偏好也存在明显差异。在主观评价中发现,根据电极的形状和厚度而产生的差异能被敏感地识别出来。
