Wearable EEG : What is it, why is it needed and what does it entail?
What Is it ??
The electroencephalogram (EEG) is a classic non-invasive method for measuring a person’s brainwaves and is used in a large number of fields: from epilepsy and sleep disorder diagnosis to Brain-Computer Interfaces (BCI). Current portable EEG systems, however, still have a number of drawbacks principally related to their cumbersomeness and ease of use. Wearable EEG is envisioned as the evolution of ambulatory EEG units from the bulky, limited lifetime devices available today to small devices present only on the head that can record EEG for days, weeks or months at a time. Such miniaturized units could enable prolonged monitoring of chronic conditions such as epilepsy, and greatly improve the end user acceptance of BCI systems. Results presented here from a questionnaire of neurologists indicate that there is a medical interest in the development of wearable EEG systems.

why is it needed and what does it entail?
Growing Incidence of Neurovascular Diseases
Neurological diseases are the diseases of the spine, brain, and the nerves that connect them and provides oxygenated blood. The neurovascular systems are highly dependent on the continuous supply of oxygen and nutrients, which has been supplied by the arteries and veins. The amount of oxygen and nutrients to the brain is essential for its working; therefore, a defect in the system can impair the function, and it may quickly become a life-threatening factor.
The neurovascular diseases include hemorrhage stroke, ischemic stroke, brain tumors, and more. The genetic disorders, lifestyle habits, related chronic conditions may cause the development of neurovascular diseases. During the last few years, the predominance of neurological disorders has increased significantly. For instance, epilepsy is one of the neurovascular diseases that is rising significantly across the globe.
The rising cases of brain tumors worldwide is the primary factor for the Wearable EEG devices market growth. For instance, as per the data of Lancet Neurol 2019, approximately 330, 000 cases of central nervous system (CNS) cancer were reported in the world in 2016. The most regular type of essential CNS cancer is Glioma, which is a group of malignant brain tumors that includes high-grade Glioma or glioblastoma and low-grade Glioma (astrocytoma, oligodendroglioma). Thus, it is anticipated that the increasing prevalence of neurovascular diseases is likely to fuel the growth
Significantly Rising Elderly Population
The elderly population is the group of people aged 65 and over. The increase in the aged population is poised to become one of the most important social transformations of the present time. The number of the elderly population has been rising significantly across the globe. As per the United Nations, in 2017, there were an anticipated 962 million people aging 60 or above globally, which contained 13% of the population worldwide. The geriatric population is expected to increase at a rate of 3% every year.
What Is Types And Channel ??
The wearable EEG devices based on product is segmented into 32-channel type, 14-channel type, 5-channel type, and others. In 2018, the 32-channel type segment held the largest share of the market. Moreover, the 32-channel type segment is expected to grow at the fastest rate during the coming year. The increasing usage in the 32-channel type segment is anticipated to grow in the future. Moreover, it’s various applications in recording electrical activities in the brain to detect neurological disorders and other applications in the brain-computer interface.
