Electronic device for monitoring physiological signals, healthcare system, and related methods

Abstract

An electronic device is provided. The electronic device includes sensing electrodes, reference electrodes, and amplifiers. The sensing electrodes are configured to obtain a first physiological signal and a second physiological signal different from the first physiological signal. The reference electrodes are configured to obtain a first reference signal and a second reference signal different from the first reference signal. The amplifiers are coupled to the plurality of sensing electrodes and the plurality of reference electrodes, and are configured to: subtract the first reference signal from the first physiological signal to generate a first data signal; subtract the second reference signal from the first physiological signal to generate a second data signal; subtract the first reference signal from the second physiological signal to generate a third data signal; and subtract the second reference signal from the second physiological signal to generate a fourth data signal.
