Wrist pulse gripper system

Wrist pulse signals have been practiced for the health diagnosis in Ancient Indian Medicine Ayurveda and Traditional Chinese Medicine. This simple and non-invasive approach describes the use of three finger tips for acquiring the pulse signals over radial artery around wrist of both the hands. Several degrees of controlled pressure generated by the finger tips over radial pulse points help the health practitioner in correct health diagnosis. This paper describes a prototype for the gripper mechanism to acquire such wrist pulse signals supporting the generation of controlled pressure over radial pulse points. The whole system is controlled with Cortex-M4 architecture microcontroller STM32F429. Mini air-motor pump is used to inflate the cuff, which is wrapped around the wrist. The pressure sensor is integrated along with the cuff to acquire the pulse signals.
