Non-contact vital signs monitor
Non-contact vital signs monitor
In 1997, the original Vital Signs Monitor (VSM) developed for the U.S. Air Force was updated and improved. The device was designed to operate at shorter distances, use a higher frequency carrier, and provide more specific heart and respiration rate information using digital signal processing techniques. The modified device operates at a frequency of 35 GHz with a corresponding wavelength of only 8.6 mm. This in turn provides a response sensitive enough to detect the small motions caused by cardiac function.
