Open up new sensing vista with innovative systems theory.

Wireless sensing of human activities and vital signs

WHAT WE DO

We develop 
system-theoretic sensing technologies for human measurement.

We develop new human measurement techniques with the establishment of innovative systems theory by combining system theory, electromagnetic theory, and medical engineering. Prior knowledge on the human body shape and vital signs is effectively used for optimizing the whole human measurement system, which is expected to break through the existing resolution limit of conventional sensing techniques.

OUR AMBITION

We explore wireless sensing frontier.

Wireless sensing of human is one of the most active research fields.
This field has been driven by our innovative idea that combines three key elements, (1) hardware, (2) software, and (3) human physiology.

Wireless Human Sensing

Although wearable sensors have been growing their popularity and market size represented by Apple Watch, radar-based wireless human sensing technology overcomes some of the main issues regarding such wearable sensors. Noncontact measurement of human activities including limb motion, gestures, unconscious motion, respiration, and heartbeat has been of great importance to a wide range of health care applications because it allows long-term monitoring of human activities without uncomfortable sensors being attached to the body. 


Because microwaves and millimeter waves can penetrate through clothing and bed tops, wireless sensing can directly measure human skin displacement in various situations unlike optical systems such as depth cameras and laser range finder systems. Wireless sensing of human activities has just begun and still a new and hot topic.

International Research Activities

All our team members are encouraged to present their research at international conferences. We have given research talks more than 270 times so far including all meetings, symposia and conference in Japan and other countreis. We have also been working together with other institutions  including Delft University of Technology, Delft, the Netherlands and University of Hawaii at Manoa, Honolulu, HI, USA. Students in our group have an opportunity to visit these overseas institutions to be a part of international joint research projects.
