Systems and methods for collecting fluid from a subject

This device collects bodily fluids like blood or interstitial fluid directly from the skin. It uses tiny needles to gently break the skin's surface, along with a vacuum to draw the fluid into a storage chamber. The device also features internal walls to guide the fluid and an interface that pulls the skin closer when the vacuum is applied.

Why it matters: Since 2020, manufacturing techniques for microneedle arrays have become more scalable and precise. This enables more effective, less invasive fluid collection for diagnostics, particularly interstitial fluid analysis.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedMicroneedles, custom fluidics, vacuum mechanism
