The invention discloses an object, a method and a system for detecting heartbeat or whether an electrode is in good contact. The heartbeat is detected by arraning multiple textile electrodes on the texitle, using ECG equipotential line diagram, considering interference caused of human movement, and designing a seperating electrode structure, electrode position, area and lead layout in an innovative manner; the dry electrode or capacitive coupling electrode is selected along with the change of environmental state so as to pick up the ECG signals; the contact bewteen the electrode and the human body can be detected whether it is in a good state or not by measuring the noise, body surface impedance, muscle impedance and the like; in addition, the posture and action of human body can be speculated according to the wave mode and noise of the ECG signals. |
