近几十年来，可穿戴电子产品已将成功的生物医学产品引入商业市场，包括实时监测，症状诊断，刺激治疗和康复。水凝胶电极通常用于此类设备中，用于数据采集或电干预。然而，长期使用它们并不是一个舒适的选择，而且可能引发过敏反应。因此，人们正在积极研究低成本的纺织电极，以替代水凝胶标准。在这项工作中，我们研究了在皮肤和基于纺织品的电极之间放置不同电解质层（水、油包水（W/O）霜和水包油（O/W）霜）对经皮神经电刺激（TENS）期间接触阻抗的影响。采用电极组织阻抗（ETI）和归一化互相关（NCC）分析方法对电解液和水凝胶织物电极的性能进行了评价和比较。研究表明，在短期使用中，带有O/W乳膏的纺织品电极是水凝胶标准的可行、有效替代方案，而W/O乳膏则是一些长期应用的可能解决方案。
Over recent decades, wearable electronics have introduced successful bio-medical products to the commercial market, including real-time monitoring, symptom diagnosis, stimulation therapy, and rehabilitation. Hydrogel electrodes are commonly used in such devices, for data acquisition or electrical intervention. However, they are not a comfortable option for long-term applications and can trigger allergic reactions. Therefore, low-cost textile electrodes are actively being researched as an alternative to hydrogel standards. In this work, we study the efficacy of different electrolyte layers (water, water-in-oil (W/O) cream, and oil-in-water (O/W) cream), placed between the skin and textile-based electrodes, on contact impedance during transcutaneous electrical nerve stimulation (TENS). Both electrode-tissue impedance (ETI) and normalized cross-correlation (NCC) analyses were used to evaluate and compare the performance of textile electrodes with electrolyte to hydrogel electrodes. The study revealed that textile-based electrodes with O/W cream present a viable, effective alternative to hydrogel standards for short-term use, whereas W/O cream presents a possible solution for some longer-term applications.
