Acquisition and Analysis of Biomedical Signals in Case of Peoples Exposed to Electromagnetic Fields

Abstract

Abstract. In this paper we present studies on biological and health effects of electromagnetic fields emphasising the aspects related with measurement of the aggressing electromagnetic fields. A brief review of literature on electromagnetic environment is presented, together with some methods aiming to control and eliminate the electromagnetic interferences on medical instrumentation used in the acquisition of the biological signals (electroencephalography -EEG, electrocardiography -ECG). We performed analysis of electromagnetic fields in order to determine the induced current/field and the specific absorption rate in models of human body and also to correlate the exposure fields with some alterations of the biological signals acquired from a subject laid in various electromagnetic environments. The main goal of this research is to design a method for accurate identification and characterization of the aggressing electromagnetic fields on biological signals and human health.
