Object, method, and system for detecting heartbeat or whether or not electrodes are in proper contact

摘要: Disclosed are an object, method, and system for detecting heartbeat or whether not electrodes in proper contact. The is multiple textile that arranged on a product, where isopotential surface map of electrocardiogram (ECG) used, interference caused by movements human body considered, as structure separated electrodes. capable the basis positions areas electrodes, arrangement conductive cables, selecting, according to changes state environment, dry cell powered- capacitively coupled-electrodes acquire electrocardiography signal. contact with measuring noise, resistance, muscular inferring posture ECG signal noise.
