Product description
The BioDeviceLab Wearable Absorptive Microfluidic Sensing Patch is a fully self-contained, flexible platform designed for passive collection and analysis of biofluids such as sweat or interstitial fluid. An integrated absorbent pad positioned at the skin interface continuously wicks fluid into the microfluidic network, eliminating the need for external pumps, tubing, or luer connectors.
Collected biofluid is guided through low-dead-volume microchannels into a dedicated sensing chamber housing an embedded electrochemical or chemical sensor. The optically transparent, multilayer polymer structure enables real-time visualization while maintaining comfort and mechanical compliance during wear. The compact, adhesive-backed design supports stable operation under daily motion, enabling continuous or time-integrated monitoring at the point of use.
This platform is optimized for wearable diagnostics, continuous physiological monitoring, and fully untethered sensing applications.
