Wrist Pulse monitoring has recently gained a lot of attention in the scientific community because it is thought to be a good predictor of human health status. The pulse is a "vital sign," or one of the most basic medical characteristics. The abnormal form and rhythm of arterial pulse are linked to a variety of diseases. In our radial artery, a total of three types of pulses are exist, namely Vata, pitta, and Kapha respectively which are collectively known as tridosha,' and optimum health is defined as a balance between these three doshas. Traditional pulse analysis necessitates extensive pulse examination experience as well as a high degree of expertise. The interpretation is usually subjective, depending on the practitioner's level of knowledge. As a result, it is necessary to build a reliable monitoring method capable of capturing the radial artery pulses. The majority of current pulse diagnosis devices are contact type, which have a few drawbacks. Due to their high sensitivity, optical sensors are a viable alternative for precise measurement. In this project a pulse measurement system that can measure radial artery pulses in a non-contact way will be developed using CMOS image camera. In addition unintentional motion generated by patients due to fever or any other reasons may affect the original pulse signal measure by CMOS camera. In order to eliminating this unusual noise MARG sensor unit will be use. The data from the CMOS sensor and MARG (Magnetic, Angular Rate, and Gravity) sensor module is acquired by NI-cRIO, and the original pulse vibration is obtained by subtracting the MARG sensor data from the CMOS camera data. Using this we can monitor the pulse movement in real-time.
