MED Probe (MEA)

Microelectrode array (MEA) with the industry’s lowest-impedance electrodes

Med Probe

The MED Probe has multiple microelectrodes embedded in the center of a transparent glass plate. The surrounding glass (or plastic) cylinder makes the MED Probe a self-contained recording chamber.

The MED Probe features the industry’s lowest-impedance electrodes (10 kΩ at 1 kHz for 50 μm electrodes). It provides excellent signal-to-noise ratio and capabilities of stimulation.
