Our study investigated the efficacy and feasibility of screen-printed and ink-printed textile-based dry electrodes for electromyography (EMG) acquisition, marking a novel step in wearable telehealth (TH) system integration. We controlled the design and fabrication conditions of these textile EMG sensors, including electrode area and sizing, ensuring optimal contact pressure. Skin-electrode impedance for all designs was evaluated, and a 20 mm electrode diameter was deemed material-efficient and design-effective. When compared with standard 20 mm wet electrodes, our EMG sensors with the screen and inkjet-printed dry electrodes exhibited comparable signal-to-noise ratios (SNR) to the conventional wet electrode (26 dB) with a peak of 25 dB, and 23 dB, respectively, emphasizing their reliability. Our research identified a 10% optimal strain by sizing for EMG performance across both printing techniques. These revelations support the future design of dependable, reusable dry textile electrodes, addressing challenges faced by wet electrodes. Additionally, the developed dry electrodes, when equipped with a Bluetooth-enabled amplifier puck mitigate common EMG challenges such as motion artifacts while promoting user comfort, which leads to an elevated user experience during EMG biosignal collection. The integration of the developed garment-based electrodes with available commercial technologies holds promise for enhancing TH systems and user engagement in wearable health monitoring.
我们的研究调查了用于肌电图（EMG）采集的丝网印刷和喷墨印刷的基于纺织品的干电极的有效性和可行性，这标志着可穿戴远程医疗（TH）系统集成迈出了新的一步。我们控制了这些纺织EMG传感器的设计和制造条件，包括电极面积和尺寸，以确保最佳接触压力。评估了所有设计的皮肤-电极阻抗，20毫米的电极直径被认为在材料利用和设计方面是有效的。与标准的20毫米湿电极相比，我们带有丝网印刷和喷墨印刷干电极的EMG传感器分别具有与传统湿电极相当的信噪比（SNR），峰值分别为25dB和23dB，突出了它们的可靠性。我们的研究通过确定两种印刷技术中EMG性能的最佳尺寸，发现了10%的最佳应变。这些发现为可靠、可重复使用的干纺织电极的未来设计提供了支持，解决了湿电极面临的挑战。此外，开发的干电极配备蓝牙放大器圆盘时，可减轻诸如运动伪影等常见的EMG挑战，同时提高用户舒适度，这在EMG生物信号采集期间带来更高的用户体验。将开发的基于服装的电极与现有的商业技术集成，有望增强TH系统以及用户在可穿戴健康监测中的参与度。
