Wearable sensors are becoming a promising tool in personalized health care and exercise monitoring. In a recent study, researchers from Japan have developed a novel wearable chemical sensor capable of measuring the concentration of chloride ions in sweat. By using a heat-transfer printing technique, the proposed sensor can be applied to the outer surface of common textiles to prevent skin irritation and allergies, and could also be useful in the early detection of heat stroke and dehydration.
