Abstract

A method is disclosed of detecting an output signal that is representative of an alternating electrical signal from a subject. The method includes the steps of: providing a monitoring sensor on the subject, wherein the monitoring sensor includes a conductive element and a composite material that includes a polar material that is substantially dispersed within a polymeric material; receiving the alternating electrical signal from the subject such that the composite changes its dielectric constant responsive to alternately ascending and collapsing voltages of the alternating electric signal from the subject; and providing an output signal via the conductive element responsive to changes in the dielectric constant of the composite that are representative of the alternating electric signal from the subject.
