Up to 32 penetrating electrodes surrounding one or more optical fiber.

Custom length of each electrode and optical fibers between 1 to 40 mm, including different lengths within the array.

Custom spacing between electrodes is in the range of 0.1-1mm

Custom microelectrode impedance for individual electrodes ranges between 10kΩ-5MΩ.

Custom electrode tip diameter between 1 – 6 µm.

Custom reference and ground electrodes according to the researcher’s requirements.

Optionally integrated fiber optic and/or drug delivery cannula.

Parylene-C electrode insulation.

Pure Iridium is suggested for chronic stimulation studies.

The fiber optic is positioned in the middle of the array, its vertical position is custom and its receptacle is compatible with most of the light sources.

The small-scale but high-density arrays provide multichannel Single-Unit (SUA), Multi-Unit (MUA) and Field Potential (FP) data leading to consistent and high-quality results.
