Wearable mental stress evaluating device and method

The invention discloses a wearable mental stress evaluating device and method. The wearable mental stress evaluating device comprises a physiological data sensor module, a data recording module, a data analysis module, a display module and a power supply module, wherein the physiological data sensor module is used for transmitting measured physiological parameter signals to the data recording module; the data recording module is used for converting the measured physiological parameter signals to obtain physiological parameter data; the physiological parameter data is transmitted to the data analysis module; the data analysis module is used for analyzing the physiological parameter data through an individual physiological-mental model, and used for transmitting analysis result to the display module for display. By adopting the wearable mental stress testing device and the method, precise quantitative evaluation on mental stress is realized, due to the establishment of the individual physiological-mental model, the evaluation on the mental stress can better conform to the individual physiological signal characteristics of a target user, and better evaluation output is obtained.
