The paper presents the development of prototype system for measurement of vital functions using the transthoracic bioimpedance. The measurement of the bioimpedance is a non-invasive method providing the information about the body composition, hearth rate, blood flow, breathing etc.

The design and realization of a simple four electrode system have been done. The device is designed as a combination of a signal generator with stabilized current output and a measuring amplifier based on the AD620 amplifier.

The output signal includes information about the basic vital signs and could be used as a part of telemonitoring system for the elderly and persons after the organs failure. The device will be used for research and educational purposes in the Smart Home facility at the Czech Technical University in Prague.
