Low Cost Analog EEG amplifier for Healthcare Applications

Patients with epilepsy experience difficulties throughout their lives and need to be careful in managing their condition. Seizures can cause serious injury or be life-threatening when crossing heavy machinery (such as when driving a car). Electroencephalographic signals are used to determine the brain's actions during seizures and as a result of complex skin preparation techniques. This model offers a portable design that integrates data from a set of AgCl electrodes with a reference electrode. The model includes an instrumentation amplifier, low-noise and high-impedance filters. The experimental results show that the system could implement the acquisition and store the EEG signals efficiently.
