The invention comprises a system of wearable devices that collectively allow for the continuous, non-invasive, measurement and monitoring of blood pressure, without the use of an inflatable cuff. The system incorporates: 1) An optical module, which is comprised of a coherent source of light, a semi-transparent hologram, microscope optics for viewing the interference pattern developed between the illuminated hologram and arterial blood, a spatial light modulator (SLM), and processing electronics with Bluetooth capability that facilitates digitization and wireless transmission of the fringe pattern to, 2) a personal digital assistant (PDA) that is worn on a waist belt. The PDA and associated software allow for continuous calculation and monitoring of real-time arterial blood pressure from the digitized fringe patterns received. The system further comprises 3) a personal computer (PC) with wireless capacity and connection to the internet. Continuous BP function, alerts, condition and medical assessment is conducted through PDA-PC communications with internet based medical facility.
