A Miniaturized ECG System Based on a Versatile Single Chip Sensor Interface

Commercial low-cost ECG electrodes and custom integrated electronic circuits can be combined to build a compact system capable of performing both the EGC and bioimpedance measurements. This paper presents a compact solution for ECG and bioimpedance acquisitions relying on a recently introduced versatile low-power mixed-signal sensor interface, without using complex algorithm of acquisition and signal processing. Experimental test were conducted on a prototype to evaluate the capability of measuring biomedical signals.
