The present invention discloses a mm-wave radar sensor to be deployed as emotion sensor, being inherently small size, and being able to be produced in low cost manner. The key system relevant components are utilization of mm-wave integrated radar, specific planar high-gain antenna radiation patterns, and analyzing the vital signs of objects by the same apparatus. The objects are human beings with vital signs vibrations, and animals with vital sign vibrations, where the system calculates and detects the frequency of vital sign rates: heartbeats and respiration frequencies. The values of vital signs rates as well as the changes of vital sign rates are used together with objects vital signs profile to calculate the emotion value. Emotion value may be additionally enhanced by specific movement pattern events added additionally in the emotion status evaluation. Emotion value can be information about object mood or simple alert of the excitements or calmness, as well as information of the increased or decreased excitement. Preferably, the proposed apparatus is using 60 GHz ISM Band integrated radar front, working in Doppler mode. Physical size of proposed apparatus in range: 4×2×1 cm or smaller.
