Abstract
A non-contact system utilizing an air-propagated ultrasound for monitoring biometric parameters is disclosed. A non-contact sensor transmits an ultrasonic wave toward a subject. The wave is reflected by the subject'"'"'s skin surface back toward the sensor. Electronics in the sensor measure the small changes in displacement of the skin surface to derive a plurality of biometric parameters, including but not limited to respiration rate, heart rate, eye motion, and limb movement.
