Smart electronic wrist device worn by human subjects for wireless heart rate monitoring in real-time

A method wirelessly monitoring a heart rate with a smart electronic wrist device in real-time with while worn by a human subject, the method comprising:

• securing the smart electronic wrist device to the human subject with a wristband;
• attaching the heart rate sensor to the wristband for contact with the human subject;
• generating, with a heart rate sensor, electronic signals responsive to the heart rate of the human subject in real-time;
• receiving, in an analog-to-digital signal converting circuit (ADC) electronically coupled to the heart rate sensor, the electronic signals generated by the heart rate sensor;
• converting, in a digital signal encoding circuit electrically coupled to the ADC, the electrical signal to a data signal;
• and
• transmitting, with a wireless communication interface, the digital signal wirelessly to a handheld cellular device,
• wherein the handheld cellular device includes a physiological processor for analysis of the data signal concerning the heart rate of the human subject.
