Flexible and durable – Fabricated with our polymer MEMS technology, our ECoG arrays can conform to the brain surface.
Optimized array designs – Select from a variety of ECoG array designs featuring different site spacings, for different applications or animal models.
Versatile – Combine an ECoG array with a NeuroNexus penetrating array to establish concurrent surface and intracortical interfaces.

“The chronic version of the Micro-ECoG electrodes from NeuroNexus made our implant procedure on the cerebellum much easier and more reliable. Electrode breakage is no longer a problem.”
