Survey of Wearable Sensors with Comparative Study of Noise Reduction ECG Filters

Abstract

Wearable sensors are the major part of Wireless Body Area Networks (WBANs) for provision of health care services and physical activity monitoring. In this paper, a brief survey of different types of wearable sensors presented along with sensor placement. Designing of wearable sensors for ECG and Blood pressure also discussed. Comparative study of FIR and IIR noise reduction ECG filters discussed at the end. With the help of MATLAB R2008b, different types of FIR and IIR filters designed to remove Baseline Wander Noise, Muscle Noise and Power line Interference from raw ECG signals of different subjects and have compared which filter provides best result.
