Durability Study of Embroidery Electrode Made of Stainless Steel Blended Yarn

Abstract

“Tatami” is the most commonly used needle type in computer embroidery. Its uniform yarn, contact point and gap arrangement can greatly reduce the resistance of fabric electrodes (0.65 MΩ–4.9 MΩ) and the impedance between electrodes and human skin (2.455 MΩ), which can meet the requirements of intelligent wearable devices for long-time electrocardiogram monitoring. In this work, properties of a fabric electrode were tested. Its air permeability and wear resistance are good, although human sweat will lead to different degrees of resistance of stainless steel embroidery electrode. It will not change its performance too much. Generally speaking, the wearing performance and ECG (electrocardiogram) monitoring performance of the stainless steel embroidery electrode are stable.
