In the ever-evolving landscape of wearable technology, a groundbreaking development is poised to revolutionize how we monitor and analyze sweat, with profound implications for the energy sector. Researchers from Mines Saint-Etienne, Centre CMP, Département BEL, have unveiled a novel approach to on-garment sweat sampling using vertical textile microfluidics, a method that promises real-time biosensing and advanced point-of-care diagnostics.
At the heart of this innovation is Marina Galliani, the lead author of the study published in npj Flexible Electronics. Galliani and her team have harnessed the power of stereolithography (SLA) 3D printing to create epidermal microfluidics within textiles. This technique involves using flexible SLA resin to define impermeable fluid-guiding microstructures in textile microfluidic modules. The result is a system that reduces the device footprint and required sample volume, making it ideal for on-body fluid collection, storage, and transport.
The vertical stacking of these modules is a key feature, allowing for a pressure gradient that provides a vertically distributed, capillary-driven sweat flow. This flow is guided by the wicking power of the textile structure, ensuring continuous sweat transfer and evaporation. “The vertical stacking not only minimizes the space required but also enhances the efficiency of sweat collection and analysis,” Galliani explains. “This makes our system highly suitable for integration into everyday apparel, providing a seamless and non-intrusive monitoring experience.”
The implications for the energy sector are vast. Real-time monitoring of physiological biomarkers in sweat can lead to the development of wearable devices that track the health and performance of workers in high-stress environments, such as oil rigs or power plants. These devices can alert workers and supervisors to potential health issues before they become critical, thereby improving safety and productivity.
Moreover, the ability to analyze sweat in real-time can provide valuable data for optimizing work schedules and ensuring that workers are operating at peak efficiency. For example, monitoring electrolyte levels can help in preventing dehydration, a common issue in physically demanding jobs. “By integrating these microfluidic systems into workwear, we can create a proactive approach to health monitoring, which is crucial in high-risk industries,” Galliani adds.
The modular approach of this technology also allows for multi-parameter detection, making it versatile for various applications beyond the energy sector. For instance, it can be used in sports science to monitor athletes’ performance and health, or in healthcare to provide continuous monitoring for patients with chronic conditions.
The use of rapid additive manufacturing further enhances the appeal of this technology. It enables quick and cost-effective production of these microfluidic systems, making them accessible for widespread use. “The ability to produce these devices rapidly and at scale is a game-changer,” Galliani notes. “It opens up possibilities for personalized healthcare solutions that were previously unimaginable.”
As we look to the future, the integration of vertical textile microfluidics into wearable technology holds immense potential. It represents a significant step forward in the field of biosensing, offering a non-invasive, efficient, and real-time method for monitoring physiological biomarkers. For the energy sector, this technology could lead to safer work environments, improved worker health, and enhanced operational efficiency. As research in this area continues to evolve, we can expect to see even more innovative applications and advancements, driven by the pioneering work of researchers like Marina Galliani and her team.
