Low cost EEG signal acquisition system

Biomedical engineering technology research of late is focusing on the rapidly growing inter-disciplinary area of affordable healthcare, to promote evidence-based information and evaluate the low-cost healthcare technologies. With an ever increasing cost of medical diagnostics, and an increasing demand by individuals to access consumer-level products, there has been an explosion of low-end health technology, such as Micro Health applications on mobile phones. However, much of the technology still requires more scientific evidence for its suitability and efficacy. Moreover, technologies for resource-constrained locations often fail to take into account the social, economic and infrastructural issues such as, social acceptability, long-term compliance, available supply chains and economic sustainability plans. Against this backdrop presented a low cost EEG/EeG system suitable for real time monitoring and transmission of signals using the widely available GSM network.
