| Outline of Final Research Achievements |
We have developed “Stress measuring chair” and evaluated its efficiency. The micro Doppler radar (24GHz, 7mW) with planar patch antenna was attached to the back of the chair. The radar detects tiny movements on the body surface caused by heartbeat in non-contact way and from its RR intervals, we calculated HVR which indicates autonomic activities. In the test with a help of a psychiatrist, patients suffering from depression and normal subjects were instructed to relax on the chair with natural sounds and images. As the result, parasympathetic activities did not show apparent increase among the patients while it significantly increased in the normal control subjects. We were successfully able to practice primary stress monitoring by only inducing relax state.
