Review of wireless Polysomnography System

Abstract

In last years , the number of people suffering from sleep disturbance has increased. Traditional polysomnography (PSG) in hospitals or sleep centres records many physiological signals while a patient is sleeping in order to diagnose sleep disturbances. But the enormous number of connected wires needed for conventional PSG is typically one of the main problems that result in sleep disruptions. Traditional PSG devices are not suitable for sleep monitoring at house due to their high cost and big body size. In this review paper, it cover the wireless techniques which used to recorded physiological signal during sleep. Wireless PSG developed systems can be used at home or in the hospital. These techniques could make a PSG test less challenging in particular situations, eliminate the requirement for hospital or healthcare overnight stays, and make self-setup and internet-based diagnostics easier
