Development of 32 Channel EEG Telemetry

This research will study the possible use of infra-red and spread-spectrum telemetry techniquesfor long-term EEG monitoring with up to 32 channels. The specific aim is to develop an EEG telemetrysystem that can be comfortably worn by mobile patients for at least 24 hours and can transmit 200hertz, 12 bit resolution EEG data from up to 32 channels using one or a combination of the twomethods. Feasibility studies will include surveys of infra-red and radio spectrums at hospital sites, andpreliminary breadboard systems to evaluate transmitter power for dropout-free signal transmission. Itis likely that infra-red telemetry will utilize patient tracking in order to achieve satisfactory signal to noiseratios. The goal will be to design systems that can be manufactured and sold for less than $10,000.00more than comparable cable telemetry.
