Product description
The BioDeviceLab Forehead-Mounted Smart Microfluidic Sensing Patch is designed for continuous, non-invasive monitoring of sweat-based biomarkers at the forehead, a site with reliable sweat production and minimal motion artifacts. The flexible, transparent patch conforms seamlessly to facial contours, ensuring stable skin contact and user comfort during extended wear.
An integrated absorbent pad passively collects sweat at the skin interface and directs it into a low-dead-volume microfluidic network. The collected fluid is routed to an on-patch sensing chamber coupled with embedded electronics for signal conditioning, processing, and wireless data transmission. The transparent microfluidic architecture enables direct visualization of fluid transport while maintaining a low-profile, unobtrusive appearance.
This platform is well suited for continuous physiological monitoring in clinical, athletic, and research settings, including applications where head-mounted placement offers superior signal stability.
