This project is done to develop a cheap and fast olfactory test method to diagnose amnesia early. It aims to introduce a new medical model that provides patients with timely detection and consultation services. In this way, patients in the incubation period can be more aware of the coming of the disease and have more time and opportunities to cure Alzheimer’s disease. People can use the test box to self-detect the current level of smell and rely on the APP to complete the process of online consultation, one-click registration, and door-to-door delivery of medicines, which can effectively reduce the waiting time for treatment and solve the patient’s smell problem immediately.
