Self-Diagnosis Device Using Wrist Pulse

To diagnose disease, western medicine looks inside of patient´s body using many devices such as MRI, but oriental medicine only observes outside of patient´s body. A pulse signal is one of those examples. A wrist is good part of our body to detect a pulse signal and the wrist pulse has been used as a fundamental element for diagnosis in Traditional Chinese Medicine (TCM). It has many properties and by perceiving these features, doctors can diagnose disease. In this paper, we have developed diagnosing system which detects pulse signal using piezoelectric film sensor and uses pulse to check possible liver illness and heart disorder.
