Bibliographic Information

• Subject Area: Design of Wearable Health Monitoring Devices and Human-Computer Interaction
• Keywords: Wearable Technology, Electrocardiogram (ECG), Smart Textiles, Motion Artifacts, Iterative Design, Gender Equity, Anthropometry, Health Monitoring

Research Background and Problem Statement

• Identified Issues or Challenges: Current wearable biosignal monitoring devices are predominantly designed based on male anthropometric data, often neglecting female anatomical features such as the presence of breast tissue. This results in poor adaptability of devices for female users, exacerbating gender disparities in wearable technology usage.
• Significance: Health monitoring devices that account for women's unique anatomical characteristics can more equitably improve health outcomes for users of different genders. Furthermore, advancing human-computer interaction technologies requires broader user and body feature considerations to optimize real-world usability.
• Research Motivation and Related Work: Gender bias has been identified in fields such as engineering, technology, and sports science, but solutions addressing this issue remain limited. Previous approaches often overlook unique body structures, particularly the impact of breast tissue on signal quality and comfort in health monitoring devices.

Proposed Solution

• Proposed Solution: This study introduces "ARGONAUT," a female-specific ECG monitoring garment that leverages innovative textile electrodes and compression garment technology to achieve high-quality health data collection. The research systematically explores materials, construction, and garment assembly to optimize wearability and signal quality.
• Innovative Contributions:
  1. Proposes a health monitoring garment design focused on female anthropometric characteristics;
  2. Employs seamlessly integrated textile electrodes within clothing to enhance comfort and "social wearability";
  3. Optimizes critical aspects of wearable ECG devices through iterative design, including compression layer design, closure mechanism improvements, and the use of foam padding.
• Implementation Steps:
  1. Investigate the adaptability of existing ECG monitoring systems to female anatomical features;
  2. Develop garments tailored to female body characteristics through prototype design and iterative optimization;
  3. Test the design with four female participants to evaluate signal detection performance, noise interference, and user experience.

Research Outcomes

• Specific Outcomes:
  1. Developed a comfortable and functional ECG garment, "ARGONAUT," featuring key design elements such as back snap closures, memory foam padding, and textile electrodes;
  2. Demonstrated that ARGONAUT performs comparably to traditional adhesive electrodes in detecting large ECG waveforms (e.g., R-wave) and shows potential for detecting smaller waveforms (e.g., P-wave and T-wave);
  3. Users rated ARGONAUT as more comfortable to wear compared to traditional ECG devices.
• Advantages Over Existing Solutions:
  • ARGONAUT addresses the adaptability issues of traditional devices for female users;
  • Integrates textile electrode technology, avoiding skin irritation caused by traditional adhesive electrodes;
  • Excels in controlling motion artifact interference, maintaining high signal quality.
• Experimental or Evaluation Results:
  • Experiments with four female participants showed that ARGONAUT reliably detected R-waves in static conditions;
  • During dynamic activities (e.g., walking, bending), ARGONAUT's noise control performance was comparable to traditional methods.
• Limitations and Future Directions:
  • The study is currently limited to a sample of women with specific body features and similar sizes;
  • Data recorded during high-dynamic activities such as jumping showed significant noise for some participants;
  • Future work should expand to a broader range of body types and focus on optimizing hardware-software interfaces and material durability.

Applications and Impact

1. Application Scenarios: Health monitoring (e.g., ECG monitoring), fitness and exercise, and even space exploration.
2. Social Significance: Promotes a more diverse and inclusive wearable design philosophy, providing customized health technology solutions for traditionally underserved populations (e.g., women).
3. Future Challenges: Developing more universally applicable garment designs and achieving high-quality signal collection in complex dynamic environments.
