Flexible three-dimensional microelectrode array for neural applications
A neural electrode array design is proposed with 3 mm long sharpened pillars made from an aluminumbased substrate. The array is composed by 25 electrically insulated pillars in a 5 x 5 matrix, in which each aluminum pillar was precisely machined via dicing saw technique. The result is an aluminum structure with high-aspect-ratio pillars (19:1), each with a tip radius of 10 μm. A thin-film of pl...
متن کاملPlateau-Shaped Flexible Polymer Microelectrode Array for Neural Recording
Conventional polymer multielectrode arrays (MEAs) have limitations resulting from a high Young’s modulus, including low conformability and gaps between the electrodes and neurons. These gaps are not a problem in soft tissues such as the brain, due to the repopulation phenomenon. However, gaps can result in signal degradation when recording from a fiber bundle, such as the spinal cord. Methods: ...
متن کاملSurface-modified microelectrode array with flake nanostructure for neural recording and stimulation.
A novel microelectrode modification method is reported for neural electrode engineering with a flake nanostructure (nanoflake). The nanoflake-modified electrodes are fabricated by combining conventional lithography and electrochemical deposition to implement a microelectrode array (MEA) on a glass substrate. The unique geometrical properties of nanoflake sharp tips and valleys are studied by op...
متن کاملAn active, flexible carbon nanotube microelectrode array for recording electrocorticograms.
A variety of microelectrode arrays (MEAs) has been developed for monitoring intra-cortical neural activity at a high spatio-temporal resolution, opening a promising future for brain research and neural prostheses. However, most MEAs are based on metal electrodes on rigid substrates, and the intra-cortical implantation normally causes neural damage and immune responses that impede long-term reco...
متن کاملA Multi-Channel, Flex-Rigid ECoG Microelectrode Array for Visual Cortical Interfacing
High-density electrocortical (ECoG) microelectrode arrays are promising signal-acquisition platforms for brain-computer interfaces envisioned, e.g., as high-performance communication solutions for paralyzed persons. We propose a multi-channel microelectrode array capable of recording ECoG field potentials with high spatial resolution. The proposed array is of a 150 mm2 total recording area; it ...
