Smart Textiles: How Clothes Could Track & Improve Your Health
Could the clothes we wear one day monitor our health and even power our devices? Researchers are increasingly focused on “smart textiles” – fabrics embedded with technology capable of tracking vital signs, movement and even generating energy. A recent review, published in ACS Omega, highlights the potential of a new material called MXene to transform everyday clothing into sophisticated health monitoring and power-generating systems.
MXenes: A New Frontier for Smart Fabrics
At the heart of this innovation are MXenes, a class of two-dimensional materials composed of metals. These microscopic materials can be coated onto or printed directly onto fabrics, imbuing them with a range of capabilities. Joyjit Ghosh, a doctoral student at the University of Georgia’s College of Family and Consumer Sciences and the corresponding author of the study, explains that MXenes possess “advanced properties.” They can detect body temperature, blood pressure, and heart rate, but likewise exhibit antimicrobial qualities, making them particularly promising for use in healthcare settings.

The research team conducted a comprehensive analysis of hundreds of published studies to understand the diverse properties of MXenes and how they could be applied in smart textiles. This review builds on a growing body of work exploring the potential of smart textiles for personalized healthcare, as detailed in a 2022 Nature article examining platform technologies and clinical applications.

Health Monitoring and Beyond
The potential applications for these smart textiles are wide-ranging. Wearers could track their own health metrics, while doctors and healthcare professionals could remotely monitor patients’ vital signs, receiving alerts if irregular heart rates, blood pressure fluctuations, or temperature changes are detected. This continuous monitoring could be particularly valuable for individuals with chronic conditions or those recovering from illness.
Beyond monitoring, these fabrics could also actively respond to the body’s needs, helping to regulate body temperature. The antimicrobial properties of MXenes could also prove invaluable in hospital environments, reducing the risk of bacterial contamination. Ghosh notes that “if we use MXene-coated textile materials, we will get those antimicrobial properties, which are needed in hospitals.”
Powering Wearables with Sunlight
Perhaps one of the most exciting aspects of MXene-based smart textiles is their ability to generate and store energy. Unlike traditional wearables like smartwatches that rely on external batteries, these fabrics can harvest energy from sunlight. This solar power could not only operate the sensors embedded within the fabric but also function as a built-in power bank.
“We can store the energy we’re getting from the sun,” Ghosh says. “If we want, we could put our cellphone in our wearable textiles so that it can be charged. The fabric would have thin energy harvesting and storage layers built directly into it, functioning like a flexible, wearable power bank that could charge a phone or even a laptop in the near future.” This concept aligns with broader advancements in self-powered smart textiles, as highlighted in a review published in the Chemical Engineering Journal, which explores various technologies for generating power from human movement and the environment.

Challenges and Future Directions
Despite the promising potential, MXene-based smart textiles face several challenges. The review found that these materials can degrade when exposed to oxygen or water, potentially limiting their durability and effectiveness after repeated washings. The production of MXenes currently relies on materials and processes that are not entirely sustainable.
Ghosh and his team are actively working to address these limitations. Their research focuses on improving the materials’ resistance to oxidation and developing more sustainable manufacturing methods. “We are working on how to reduce oxidation and how to prepare MXenes using some sustainable and environmentally friendly materials,” he explains. “MXenes are made from metal-based compounds that require energy intensive processing. We are trying to prepare MXenes with biodegradable materials so that we can get a sustainable product as well as one which has longer durability.”
Durability and Sustainability: Key Research Areas
The need for improved durability and sustainability is a recurring theme in the development of smart textiles. Researchers are exploring various strategies to protect MXenes from environmental degradation, including encapsulation techniques and the development of more robust material compositions. Simultaneously, efforts are underway to identify alternative, more sustainable materials for MXene production, reducing the environmental impact of these technologies.
The Broader Landscape of Smart Textiles
MXene-based textiles represent just one facet of the rapidly evolving field of smart textiles. Other technologies, such as piezoelectric, triboelectric, photovoltaic, and thermoelectric materials, are also being investigated for their potential to power and enhance wearable devices.

The development of smart textiles is also prompting discussions about data privacy and security. As these fabrics collect increasingly sensitive health information, it is crucial to establish robust safeguards to protect user data and prevent unauthorized access. Regulatory frameworks and ethical guidelines will be essential to ensure the responsible development and deployment of these technologies.
Looking ahead, the future of smart textiles appears bright. Continued research and development, coupled with a focus on sustainability and ethical considerations, will pave the way for a new generation of wearable technologies that seamlessly integrate into our daily lives, enhancing our health, well-being, and convenience.
