Microneedles are a few hairsbreadths wide and can sip the clear fluid between cells in the middle layer of skin. This is below the topmost layer of dead skin cells and above the layer of skin where veins and nerves reside. The clear, colorless fluid is called interstitial fluid and is similar to blood plasma.

Microneedles continuously sample interstitial fluid to track physiological conditions

The microneedles can contain minuscule sensors or extract the interstitial fluid for further testing. Because microneedles are tiny and don't go very deep, they're practically painless.

[...] Continual sampling of important biomarkers in this interstitial fluid could help monitor and diagnose many diseases and disorders. These markers include electrolytes, salts such as potassium and sodium that get out of balance during dehydration; glucose, a sugar that diabetics need to monitor constantly; and lactose, a potential marker of physical exhaustion or life-threatening sepsis.

    Guess we'll just have to wait a bit longer for them to start (auto-)injecting things to into soldiers and athletes as needed based on the extracted results. Combat enhancing drugs, steroids ...

    Like the meth soldiers in TNG's 'Encounter at Farpoint Station'?
