Physiological parameter(s) are determined from a biopotential having one or more signal distorting elements. The method may involve suppressing one or more signal distorting elements may be from an acquired biopotential signal by decomposing the acquired biopotential signal, identifying the one or more signal distorting elements present in the acquired biopotential signal and reconstructing the decomposed biopotential signal without the one or more identified signal distorting elements. The method may involve determining a physiological parameter by analyzing decomposed elements of an acquired biopotential signal.
Systems and apparatus for contactless measuring of biological electrical activity corresponding to an individual include an electrode capacitively coupled with a tissue surface of the individual and a high input impedance amplifier circuit for amplifying a sensing signal generated by the electrode. In some embodiments, the electrode comprises a sensing portion comprising a plurality of electrically conductive layers including a sensing layer, a guard layer and a grounding layer layered between electrically non-conductive insulating layers. Optionally, the sensing portion may also include an electrically conductive guard ring. The guard layer, guard ring and/or grounding layer may shield the sensing layer from external electromagnetic interference which may impinge on the sensing layer and/or maintain high input impedance of the high input impedance amplifier circuit. The high input impedance amplifier circuit may comprise an integrator circuit for biasing a high input impedance amplifier minimizing saturation of the high input impedance amplifier.
