Human Pulse Diagnosis (TCM)

Market Opportunity

In a Traditional Chinese Medicine (TCM) diagnosis of pulse, a TCM practitioner would use his fingertips to feel the radial arteries pulse of patients to determine their health conditions. In reference to that of the practitioner him/herself. Since it is all based on the practitioners feels, pulse diagnosis is a very difficult art to master. Only those highly experienced and “senior” TCM practitioners may know the art.


The Tri-Pulse Optical Sensor (3-POS) consists of 3 optical sensors which measure heart pulses along the radial artery in the wrist at 3 locations corresponding to the “cun”, “guan” and “chi” positions in traditional Chinese medicine.  Each sensor uses optical reflectance to monitor the volume displacement of the blood vessel as blood flow through it. A notebook computer or a Smartphone can be used for data storage and analysis.
