A conformable microelectrode array (cMEA) with integrated electronics for peripheral nerve interfacing

Abstract

A high-resolution PDMS-based conformable microelectrode array (cMEA) with integrated electronics is implemented. The cMEA is incorporated into individual layers of a nanofiber-based nerve regeneration scaffold to create a novel regenerative electrode scaffold (RES) capable of establishing a stable, high-resolution peripheral nerve interface. The device features a compact size with an enhanced signal-to-noise ratio (SNR), as required by implantation applications. Preliminary characterizations of the device are performed using in vitro experimentations, including impedance spectroscopy and neural culturing.
