Continuous glucose monitoring
A wearable sensor that reads glucose levels in interstitial fluid every few minutes, giving a continuous trace rather than a single finger-prick measurement.
A CGM places a thin filament just under the skin to read glucose in the interstitial fluid, sampling every one to five minutes and transmitting the result to a phone or watch. The trace shows not just a level but a direction and rate of change — information a static snapshot cannot give. Originally built for type-1 diabetes, the same data turns out to be useful for anyone studying how food, exercise, or sleep shifts metabolism. The hard part is accuracy: interstitial fluid lags blood by a few minutes, and sensor drift over the wear window requires either factory calibration or periodic finger-prick correction.

The FDA cleared the first continuous glucose sensor that skips the insertion needle, settling instead on a forearm patch studded with microneedles too shallow to feel.
