Design and Implementation of Multichannel Bio Signals Acquisition Device

Abstract

Bio-signals, bio-potentials or bio-electrical signals are widely employed in biomedical monitoring, e-health, psychological studies and human-computer interaction (HCI) related applications. Abundant information can be obtained from different measurements involving biopotentials, for example, electrocardiogram (ECG) for heart monitoring, Electromyography (EMG) to measures muscle response or electrical activity in response to a nerve's stimulation of the muscle and Hear beat and SPO2 for blood oxygen level[1]. In addition to the body temperature and surrounding environment condition such as temperature and humidity.
