Abstract :
In this paper, the stress status was estimated using the biosignal and fuzzy theory. Stress was estimated by `coin-stacking´ experiment with two type-relax and stress status. The estimator uses five biosignals-EMG, respiration, temperature, PPG, SCL. Fuzzy logic combines these signals and physiological knowledge. The system was tested on 10 healthy persons and achieved a template of stress progress
