THE SYSTEM FOR SENSING VITAL SINGNAL AND THE METHOD THEREOF

摘要

PURPOSE: A system and a method thereof are provided to prevent the energy loss of a bio signal by measuring the bio signal through coupling in a near field. CONSTITUTION: A signal generating part(111) generates a source signal in a specific frequency. An antenna(112) receives the reaction signal of the source signal. The antenna is an omni antenna or a yagi antenna. An extracting part extracts a bio-signal from the source signal and the reaction signal. An analyzing part(134) analyzes the property of the bio-signal. The bio-signal is either the heart beating signal of a subject or the respiratory signal of the subject. A synthesizing part synthesizes the source signal with the reaction signal.
