Abstract

EEG (Electroencephalograph) is the recording of brain electrical activity. It has numerous diagnostic and
research application in the study of brain. The main objective of the project is to build a telemetry system for
EEG. Multichannel EEG instrumentation can be prohibitively expensive for research purpose. The purpose
of the study is to design and implement a cost effective Arduino-based EEG amplifier system and transmit the
EEG through radio transceiver. The project consists of two phases. The first phase consists of designing the
EEG amplifier using IC INA118 due to its cost efficiency and Medical applications. The second phase is
designing a telemetry system using radio frequency waves which would transmit and receive up to one
kilometer. ARDUINO MEGA 2560 is used for analog to digital conversions. Thus EEG digitalized output can
be transmitted wirelessly.
