HUMAN BODY RHEOLOGY IMPACT ON MEASUREMENTS IN ACCELEROMETER APPLICATIONS

Abstract

Article present and tries to prove hypothesis that human body rheological properties can have significant impact on results that are based on accelerometry in biomechanical applications. Three experiments are conducted, mathematical model is developed and real world application is shown to support given hypothesis. During first experiment analysis of 7 body points’ acceleration characteristics is conducted. During the second experiment it is show that selected hardware (accelerometer LIS3LV02DLH) is sufficient in such applications. During third experiment it is show that human body rheology has impact on acceleration measurements in real world application. Article also presents simplified human body model (chest area) and shows its adequacy to experiment data. Finally, it is shown how much human body rheology impact real world accelerometry based calculations.
