Abstract

A wearable device applied to a human body is provided. The wearable device includes at least one sensing electrode, a conductive wire, a monitor device, and a shield element. The sensing electrode receives a physiological signal from the human body. The sensing electrode is coupled through the conductive wire to the monitor device. The monitor device is configured to process the physiological signal. The shield element includes metal fiber composition. The shield element covers the sensing electrode and the conductive wire so as to avoid electrostatic interference. The shield element is at least partially exposed to the human body.
