Recently, it is an important issue to ensure the safety of a person in welfare facilities in a huge city such as Tokyo metropolitan area, because this phenomenon is caused by the increasing number of the nuclear families.
In a welfare facility, the staffs have to repeat the patrols especially during night. This is only a visual check, and imposing a burden on the staff as well.
In order to resolve this problem, we have developed the non-contact respiration and heartbeat monitoring system using the microwave Doppler radar. Here we report the successful real-time acquisition of respiration and heartbeat data using the developed monitoring system.
