Wireless sensor networking has a crucial role to play in the progressive healthcare industry – the health monitoring systems in particular can gain a lot from this type of technology. The focus of this paper is to discuss the innovative wireless sensor network technology applied to electroencephalogram (EEG) devices alongside the paradigm used for mobile sensor networks in healthcare monitoring. Another focus of this paper is to present the technological challenges and benefits of the application of wireless EEG devices. The foundation of this method is based on the use of EEG sensors that are both miniaturized and wireless. As a result, we are able to perform ambulatory EEG recordings, which opens the door to real-time seizure detection during everyday activities. This in turn leads to a completely new stage in both medicine and research systems in general.
