Invention:
University of Arizona researchers have developed a method to print wearable sweat collection devices to that enable 24/7 sweat collection over weeks without the use of adhesives. This technology provides an easily manufacturable method for producing these devices with accurate control over channel design and integration with electrical components, enabling continuous, quantitative detection of biomarkers not possible with current technology. The invention enables FDM printing of microfluidics with soft materials for direct application on the skin without adhesives. This is enabled by a specially designed seal to capture sweat over extended periods of time, enabling a multitude of integration options. This technology can be employed in conjunction with 3D scanning and electronic mesh technology.
Background:
Epifluidics is a growing industry in medical monitoring and eccrine sweat is currently used and researched to understand more about medical conditions in the human body. The disclosed technology uses 3D printing to form the 3D channels that collect sweat from the user and detect properties within the sweat. Furthermore, the 3D printing allows for integration with electronics and therefore automated, continuous biodata from the sweat.
This technology can also be employed in conjunction with the 3D scanning and customizable electronic mesh technology developed by the same inventors to provide personalized wearable devices with a perfect fit to provide consistently accurate data for diagnostic, therapeutic and screening applications.
Applications:
- Medical studies
- Chronic condition monitoring
- Daily health monitoring
Advantages:
- No adhesive required
- Customizable
- Accessible
- Continuous sweat sampling over weeks
