Radar Sensor


We have developed portable low power radar sensors for remote noncontact detection of vital signs (heartbeat and respiration) or mechanical vibrations. Technologies to improve the performance and reduce the size for various applications are being studied. Research covers both new theory and new hardware (circuits and system). The technology can potentially be used in many different areas, including but not limited to: healthcare, veterinary medicine, search and rescue, security surveillance, and industrial applications. The following link (news release + photo + video) provides some examples of the applications:
