Product description
The BioDeviceLab Wearable Multiplex Electrolyte & Metabolite Microfluidic Patch is a transparent, flexible platform designed for continuous sweat collection and parallel biochemical analysis directly on the skin. Sweat is guided through an integrated microfluidic network into multiple isolated sensing chambers, each dedicated to a specific analyte such as lactate, potassium, pH, or glucose.
The patch supports colorimetric, fluorescent, or biosensor-based detection schemes, enabling real-time or time-integrated readout. Its low-profile, adhesive-backed construction maintains stable operation during movement, while optical transparency allows direct visual inspection or camera-based quantification. External tubing interfaces enable controlled calibration, flushing, or integration with external fluid handling modules when required.
This platform enables non-invasive, wearable monitoring of physiological status for health, performance, and diagnostic applications.
