Microelectrode arrays (MEAs) are typically interfacing an electroactive tissue with the bioelectronic systems. Printing techniques, such as inkjet and screen printing, are attractive methods for the manufacturing of a customized MEAs because they allow flexible, low-temperature, scalable, and cost-effective fabrication processes. CSEM fabricated all-printed electrocorticography arrays by inkjet printing of platinum electrodes and screen printing of polyimide as a passivation layer.
