3D-Printed Wearable Sensor 'Sweatainer' Can Collect and Analyze Sweat for Health Monitoring
Sweat tells a lot about our health. That's why collecting and analyzing it helps us monitor our physical well-being. Good thing a new device has been developed that makes sweat collection easy and convenient.
3D-Printed Wearable Sensor for Sweat Collection
Sweat is more than just a marker for an effective workout. It contains crucial data about our health, including signs of dehydration, exhaustion, blood sugar levels, and even life-threatening illnesses like cystic fibrosis, diabetes, and heart failure.
Researchers at the University of Hawaii at Manoa College of Engineering aim to make sweat collection and analysis easier by designing the 3D-printed wearable called "sweatainer," Medical Xpress reported.
According to Tyler Ray, assistant professor of mechanical engineering, 3D printing allows an altogether new design mode for wearable sweat sensors by creating fluidic networks and features with unheard-of complexity. With the sweatainer, they can demonstrate the possibilities that 3D printing offers for easily accessible, creative, and affordable development of cutting-edge wearable sweat devices.
Sweat is more than just a sign of a good workout. It holds vital information about our health, providing clues to dehydration, fatigue, blood sugar levels, and even serious conditions such as cystic fibrosis, diabetes, and heart failure.
Researchers at the University of Hawaiʻi at Mānoa College of Engineering have taken a giant leap forward in sweat analysis with an innovative 3D-printed wearable sweat sensor called the "sweatainer."
3D-printing enables an entirely new design mode for wearable sweat sensors by allowing us to create fluidic networks and features with unprecedented complexity, Department of Mechanical Engineering Assistant Professor Tyler Ray said. With the sweatainer, we are utilizing 3D printing to showcase this approach's vast opportunities for accessible, innovative, and cost-effective prototyping of advanced wearable sweat devices.
Sweatainer Allows Multi-Draw Sweat Collection
The epidermis, or outside layer of the skin, is pushed against with absorbent pads or microbore (very narrow) tubes utilizing bands or straps to collect sweat as it leaves the skin. These procedures call for skilled workers, particular handling, and pricey lab supplies.
Wearable sweat sensors have recently addressed some of these issues but are still single-use only. The device must be removed, and the sweat collection stopped when it is full.
The sweatainer's "multi-draw" sweat collecting technique, which enables the collection of multiple, distinct sweat samples for analysis either directly on the device or transmitted to a lab, is one of its special features.
This innovation was inspired by the vacutainer used for clinical blood sampling. It improves the efficiency of sweat collection and creates new opportunities for at-home testing, archiving samples for future research, and connecting the device with current health monitoring techniques.
The sweatainer system has been studied in the field, demonstrating its practical application. The researchers hope that the blueprint created by the sweatainer will continue to spur innovation and lead to a time when personal health monitoring is more widely available, practical, and insightful.
The results of the study were published in Science Advances.
