Cell phones have practically become a part of our bodies.  So Jenshan Lin thinks why not have them monitor your vital signs?  The University of Florida engineer has built a milk carton-size prototype that uses a mini Doppler radar.  He says it tracks chest movements from breathing and even heart beats up to nine feet away.  You can read your vitals on the device's EKG-like display.  Lin is confident the system can be miniaturized to fit in a cell phone and envisions pressing a button to send health information directly to your doctor's office.  He says the device's low power radio waves are both harmless and only a minor drain on batteries.  With the National Academy of Engineering, Randy Atkins, WTOP Radio.
