Abstract

Abstract : In this article, the design and development aspects of a compact bio‐potential measuring system, named ExGSense, is presented. Two versions of the prototype have been developed; first one can measure 3 + 1 V leads in time‐multiplexed fashion, while the other can measure 3 + 1 V leads simultaneously. This article also presents an efficient algorithm for filtering electrocardiogram signals which is required to attenuate the effect of motion artefacts which are inevitable in wearable systems. Further, a user‐friendly interface for PC and smartphone has also been developed. By the virtue of an ultra‐low noise instrumentation amplifier and the programmability of gain and bandwidth of the bio‐signal measuring system, a number of other bio‐potential signals like EMG, EOG and EEG have been successfully recorded using disposable, off‐the‐shelf wet Ag/AgCl electrodes.
