But when a disease or injury occurs in a certain part of the body, reaction points will appear on the corresponding acupoints on the ipsilateral or bilateral auricles. The skin resistance of this reaction point becomes relatively low, generally 20 to 100kΩ. Based on this characteristic, various types of detectors can be designed to detect the reaction points of the auricle, perform auricular acupuncture or infer the location of the disease in the human body, especially for infants and young children who cannot yet express (or cannot express accurately) their pain, it is particularly convenient and reliable to determine the location of the disease. …
