The Geodesic Sensor Net (GSN) is based on a patented geodesic tessellation technique that evenly spaces electrodes through a web-like structure. No abrasion or sedation is required. This page provides information on the GSN and related products.

Geodesic Sensor Net EGI offers two versions of its pioneering Geodesic Sensor Net: the classic GSN 200 and the new streamlined HydroCel GSN. Both come in 256-, 128-, and 64-channel configurations, sized from neonate to adult. The HydroCel GSN is also available in a 32-channel model. Below is a sizing chart, downloadable as a PDF; to the right are sensor layouts (in PDF format) for all the GSN channel counts.
