  Wearable sensors inWireless Body Area Networks (WBANs) provide health and
physical activity monitoring. Modern communication systems have extended this
monitoring remotely. In this survey, various types of wearable sensors
discussed, their medical applications like ECG, EEG, blood pressure, detection
of blood glucose level, pulse rate, respiration rate and non medical
applications like daily exercise monitoring and motion detection of different
body parts. Different types of noise removing filters also discussed at the end
that are helpful in to remove noise from ECG signals. Main purpose of this
survey is to provide a platform for researchers in wearable sensors for WBANs.
