This technique is a radio wave analogy of the bats' sonar system that analyzes more than 500 reflected waves from the human body to detect subtle movements like breathing and heartbeats. It achieves non-contact physiological detection with the slightest interference to users.
This technique is funded by the Healthy Longevity Global Grand Challenge's Catalyst Award from the National Academy of Medicine (NAM). It applies to sleep apnea detection to enable the early diagnosis of Alzheimer's Disease.
