Cardiac Surface Grids

This photo shows a 64-channel NeuroNexus Cardiac Surface Grid in place on a beating heart. Our cardiac grids are fabricated using NeuroNexus polymer MEMS technology, resulting in an ultra-flexible substrate designed to conform to the cardiac surface.

Need plunge electrodes instead? We have those, too! Contact us for available designs.

  • High recording resolution – Discover fine detail with our unique high-resolution cardiac grids.
  • Vast design space – Grids can be customized to your specific needs. Adjust size, channel count, contact density, and more. Special features can be integrated to cope with the particular demands of neurocardiology.
  • Low noise from tissue movement – Our cardiac grids have been engineered and tested to minimize noise from tissue movement.
  • Record from both surface and depth – Combine a surface grid with a penetrating probe to establish a concurrent surface and depth interface.
  • Varied applications – In addition to recording from the cardiac surface, NeuroNexus cardiac grids can also interface with a variety of nerves.

This video shows data acquired from the cardiac grid using the SmartBox data acquisition system. The SmartBox automatically maps the surface grid, and synchronizes with and displays any external peripherals. Together, NeuroNexus cardiac grids and the SmartBox offer a plug-and-play solution for any researcher performing experimental cardiac work.
