3D-Printed Wearable Microfluidic Devices for Sweat Sensing (the ‘Sweatainer’)
We are committed to pushing the boundaries of wearable technology to enhance the monitoring and analysis of physiological processes. We are excited to introduce our latest innovation: the Sweatainer, a 3D-printed epifluidic platform that offers a new level of sophistication in microfluidics design and integration. By combining advanced additive manufacturing techniques with epidermal microfluidic devices, we have developed a wearable system that can collect, store, and analyze sweat samples that utilizes device architectures not possible via other fabrication routes.

This new design space allows us to integrate more precise microfluidic valves with colorimetric assays for in situ biomarker analysis, enabling real-time monitoring of an individual's health and performance. The sweatainer operates in a mode analogous to traditional epifluidic systems, providing a seamless transition for researchers and users alike.
Sweat fills the sweatainer based upon the natural pressure generated by the sweat glands.
One of the most innovative features of the Sweatainer is its multi-draw sweat collection system. This design enables the collection of multiple, independent sweat samples for either on-body or external analysis. This new approach allows for more in-depth insights into an individual's physiological state over time, paving the way for personalized health and fitness recommendations.
