A wearable device that alerts people with food allergies before a reaction begins has the potential to reduce life-threatening anaphylaxis and transform allergy management from reactive to preventive care. The AllergE patch is a microneedle-based biosensor developed by researchers at KAUST that painlessly detects immunoglobulin E (IgE), the antibody that triggers allergic reactions, directly from the fluid beneath the skin.
