Description

Kishi, Nishitani, Kudo, and Sakata published in twenty twenty-four a sensor for lactate in sweat that works without enzymes. Lactate tracks effort during exercise, but enzyme sensors can be fragile. Their sensor uses a conductive polymer coated on a carbon electrode. A plant acid dopant makes the coating stick firmly. Chemical groups on the polymer bind lactate and gain negative charge when they do. That charge change alters the current in a measurable way.

Current tracked lactate levels across a wide range in real time. Tests accounted for acidity and other substances found in sweat. In a small flow system, the sensor read sweat taken during exercise. The value came out near sixty millimolar. The charging and discharging design offers a sturdy path to wearable sensing.
