The novel concept of a portable human stress-meter

Currently available human stress monitoring devices are either very inaccurate or rely on a strictly controlled laboratory environment. In this paper, we present the novel concept of a practical portable device for long-term monitoring of human stress in natural environment and an algorithm for calculation of the stress phenomenon. The concept envisages two synchronized blocks measuring a wider range of physiological parameters. One device will be placed on the forearm or fingers of the non-dominant hand, the other on the chest.
