Floating Microelectrode Arrays
A sophisticated neural interface that is typically best suited for chronic recording and/or stimulation in large animal cortex, the Microprobes for Life Science Floating Microelectrode Array (FMA) has also seen successful use in a variety of small animal and peripheral nerve studies. The low profile, small size, and great flexibility of the FMA make it ideal for the implantation of a large number of arrays simultaneously in the same animal, allowing a multitude of cortical locations to be targeted at the same time. Additionally, the length and impedance of individual electrodes within the same array are completely customizable, giving researchers the capability of recording multiple cortical layers and deep structures, or collecting LFP and single unit activity from the same cortical region.
The FMA is also capable of remarkably long periods of chronic use, with over seven years of continual single unit recording having been reported from multiple arrays in non-human primate.

The Floating Microelectrode Array (FMA) is based on the concept of a lightweight platform populated with rigid microelectrodes and tethered to a nano connector by a thin, flexible and light-weight cable. The platform which houses the individual electrodes is fabricated from 125 μm thick alumina ceramic, and has 18 or 36 evenly distributed holes with 400 μm (standard) or 250 μm (HD) spacing.
FMAs can be fabricated with varying electrode depths not typically achieved using planar silicon technology. Current fabrication techniques allow for individual electrode depths between 0.5 and 10 mm. Impedance values for individual electrodes within the array may be specified from 5 kOhm to 5 MOhm.
The cable is fabricated from Parylene-C insulated 25 μm diameter gold wires, which are wound in a helix for maximum flexibility and strength. The entire cable is insulated with a thin coat non-restrictive silicone elastomer, ensuring biocompatibility, flexibility and strength.
