1. An arm-based pedometer comprising:

  • an article to be worn on an arm of the user, the article having a first surface and a second surface;

    a processor;

    a powering source for the monitoring device;

    a short range wireless transceiver for transmitting a real-time vital sign signal;

    an accelerometer attached to the article, the accelerometer configured to generate a signal used as a pedometer function to determine distance traveled by the user; and

    an optical sensor for generating a signal corresponding to the heart rate of the user, wherein the optical sensor is an optical sensor comprising a light-to-voltage photodetector capable of transmitting a digital signal, and at least one light emitting diode capable of radiating light ranging from 550 nanometers to 1100 nanometers, an optical sensor comprising a light-to-frequency photodetector capable of transmitting a digital signal, and at least one light emitting diode capable of radiating light ranging from 600 nanometers to 1100 nanometers, an optical sensor comprising a plurality of light-to-voltage photodetectors capable of transmitting a digital signal, and at least one light emitting diode capable of radiating light ranging from 550 nanometers to 1100 nanometers, an optical sensor comprising a plurality of light-to-frequency photodetectors capable of transmitting a digital signal and at least one light emitting diode capable of radiating light ranging from 550 nanometers to 1100 nanometers, or an optical sensor comprising a light-to-voltage photodetector capable of transmitting a digital signal, at least one light emitting diode capable of radiating light at 567 nanometers, or an optical sensor comprising a light-to-voltage photodetector capable of transmitting a digital signal and a plurality of light emitting diodes capable of radiating green light ranging from 500 to 570 nanometers.
