including human motion monitoring, physiological monitoring, biochemical monitoring, and
multifunctional monitoring. Moreover, current strategies for integrating health monitoring systems are
explored, along with the security and reliability of their components. Despite the significant advancements
made in textile-based health monitoring systems over the past two decades, considerable challenges remain
to be addressed, spanning from material selection to system integration and eventual commercialization.

Performance improvement
In the development of textile electronics, active substances are typically endowed with specific functions
through deposition onto textile substrates or polymer fibers. However, material compatibility issues may
result in weak interactions at the interface between these active substances and their carriers, leading to a
tendency for the active substances to detach under mechanical stress such as bending, stretching, or
washing. This detachment adversely affects the operational stability of textile electronics. To enhance
stability and durability, comprehensive optimization of material selection, fabrication processes, and textile
structures is essential. For instance, improving coating techniques or utilizing more compatible binders can
strengthen adhesion between active substances and fiber substrates, thereby enhancing the reliability of
textile electronics during prolonged use. Additionally, the stability of energy storage fibers warrants
attention, as passivation of electrode surfaces and biological contamination can lead to erroneous
operational responses.

Integration
The integration of textile electronics is a pivotal step in achieving a multifunctional and efficient health
monitoring system. Through integration, a variety of functionalities such as energy harvesting, signal
processing, data storage, and wireless communication can be realized on a compact and wearable platform.
Reliable connection technologies and textile-compatible ICs contribute significantly to the high degree of
integration within electronic textiles. Although some integration technologies have been discussed in
previous sections, there remains substantial room for improvement in the current level of integration
compared to the demands of practical applications. Therefore, developing more effective integration
strategies is essential for achieving high-performance textile electronics.

Large-scale fabrications
Industry reports indicate that numerous enterprises have developed a variety of smart textile electronics.
Examples include Sergers heat socks designed for alpine skiing, Skin brand underwear capable of recording
real-time heart rate, resting heart rate, and heart rate variability, and Siren’s washable smart socks tailored
for individuals with diabetes. However, the manufacturing of these electronic textile products remains
largely confined to laboratory settings. To facilitate commercial application, a transition to industrial-scale
production is imperative. This transition necessitates not only the development of manufacturing
technologies suitable for mass production but also considerations of cost-effectiveness. Laboratory-level
manufacturing often fails to meet the cost and efficiency demands of large-scale production. Industrial
manufacturing must address issues such as automation, standardization, and quality control. Additionally,
the development of textile machinery adapted for functional fibers is crucial for realizing mass production.
For instance, traditional textile machinery may require modification or redesign to accommodate the
production of new types of textile electronics.

Health delivery
From a user-centric perspective, textile electronics must be sufficiently resilient to withstand regular use,
including daily wear and washing, and yet remain comfortable and unobtrusive for patients. Therefore,
standardized guidelines for the deployment and maintenance of these systems are essential. For these
devices to be widely adopted in healthcare, they must comply with regulatory standards for medical devices,
