||The Med-tenna, a Radar Vital-Signs Monitor, is currently available as a pager-size, handheld battery operated radar sensor. Sensitive receiver detects breathing through uniform, MOP IV, parka, etc. by simply velcro-ing the sensor to the chest.
LCD/LED displays heartbeat & breathing rates indicated on a numerical and rolling graphical output. This technology was demonstrated and tested at Texas A&M and was used at the World Trade Center in the days following 9/11.
