Wireless measurement system for continuous biomonitoring towards stress diagnostics

This contribution presents new portable electronic measurement equipment for non-invasive biomedical monitoring of selected psychosomatic processes. The main goal is monitoring of psycho-galvanic reflex of the human skin that might be very useful for identification of an undesired influence of stress in medical and psychological experiments. Thus, the integrated monitoring system, applicable also in wireless measurement environment, was designed and developed. The proposed measurement system employs methods based on measurement of physiologic parameters possibly indicating stress using smart sensors. The proposed system utilizes microprocessors with RF wireless communication module used for data transfer between the measurement unit and an acquisition point. Moreover, a graphic user interface (GUI) under Windows XP platform has been developed in order to provide necessary calibration of the measurement as well as storage, visualization and postprocessing of the measured data. The measurement methods itself as well as achieved results are discussed.
