Cardioseismometer unit based on micromechanical sensors

The report is devoted to the development of a cardioseismometer unit based on micromechanical accelerometers and micromechanical gyroscopes for noninvasive diagnostics of internal organs noninfectious diseases of a human being and the function of the heart and cardiovascular system, and also monitoring of an urgent human condition. The cardioseismometer unit measures the projections of the angular velocity and of the specific force on the chest (due to the mechanical movement of the heart upon contraction and movement of blood in large vessels) and in the result calculates the modulus of the heartbeat acceleration vector and the attitude angles in navigation frame. In the article possible circuitry and constructive solutions of the cardioseismometer unit, operation algorithm, software development and data processing are considered. The experimental research data and achieved results are provided.
