Abstract: A watch-like early allergy detection, notification and management system is equipped with a motion detector as well as one or more physiological sensors to measure heart rate, skin color change, skin galvanic response, oxygen saturation and blood pressure to detect early symptoms of an allergic reaction. False alarms are reduced by simultaneously measuring ambient temperature and physical activity of the subject. Sudden onset of skin itch, redness, sweating, increase in heart rate or a drop in blood pressure without a preceding hot ambient condition or strenuous physical activity is interpreted as an allergic reaction. The system is also equipped with a subject locator and a GPS receiver to assist a caregiver in finding the subject rapidly. The system further features a medication compartment to start managing the allergic reaction quickly. The system is particularly beneficial for children that may become scared or hide away upon onset of an allergic reaction.
