Product description
The BioDeviceLab Wearable Droplet Generation Microfluidic Patch integrates a deterministic droplet generator within a transparent, flexible platform designed for direct skin contact. The patch incorporates a precisely engineered T-junction or flow-focusing geometry that forms monodisperse droplets from converging fluid streams, as visualized directly through the optically transparent patch.
Designed for wearable operation, the patch maintains stable droplet generation under mild bending and motion while remaining lightweight and comfortable for extended wear. External tubing interfaces allow connection to reservoirs, pumps, or upstream sample collection modules, enabling continuous or time-resolved droplet workflows directly at the point of sampling. This system extends classical droplet microfluidics into wearable and point-of-care environments.
