Cori measures lactate at the skin surface using electrochemical nanotechnology. We do not pass current through your skin. Instead, we rely on passive diffusion of analytes from sweat/interstitial fluid to a selective sensing layer, then convert molecular binding into an electrical signal the device can read.
Our body naturally exudes a mixture of sweat and interstitial fluid (ISF), the sample matrix, which contains ions and molecules in very small quantities. Cori accesses analytes from this matrix by passive diffusion, where lactate and ions naturally migrate toward the sensor interface without any skin puncture or pumping. The sensor also creates a very small electromagnetic field that polarizes ions within the sample matrix beneath the skin, drawing those ions—along with the target molecule, lactate—toward the sensor surface. No electrical current is passed through the skin.
The sensor surface is coated with lactate-specific linker molecules. When lactate arrives, it binds to this layer via an electrochemical reaction, releasing electrons that are converted to an electrical signal. Because the sample matrix is ultra-dilute with low analyte concentration, the raw signal would be difficult to detect without an on-sensor transducer.
Small electrical signals are converted into a readable output by a Graphene Field-Effect Transistor (FET) integrated directly beneath the sensing layer. Binding-induced surface charge modulates the local electric field and carrier density in the graphene channel, providing field-effect amplification inside the sensor. The amplified signal is then digitized and corrected for temperature, motion, and baseline drift before streaming to the app for real-time visualization and analysis—enabling detection of very low lactate concentrations from an ultra-dilute sample, without needles.
Real-time lactate, not guesswork.
The device continuously samples the sensor output and performs on-body filtering and stabilization. Data is transmitted securely to the Cori app via a low-power wireless link. The app displays live lactate, session markers (splits, intervals), and context signals (e.g., temperature, motion). Cori's modeling layer interprets the curve to flag threshold crossings, fatigue inflection, and recovery status, then summarizes the session into actionable recommendations.
