Abstract

A hybrid bioelectrical interface (HBI) device can be an implantable device comprising an abiotic component operable to transmit charge via electrons or ions; a biological component interfacing with the neural tissue, the biological component being sourced from biologic, biologically-derived, or bio-functionalized material; and a conjugated polymer component that together provide a way to chronically interface living neural tissue with electronic devices for extended durations (e.g. greater than 10 years). In some embodiments, conjugated polymers provide a functional electrical interface for charge transfer and signal transduction between the nervous system and an electronic device (e.g. robotic prosthetic limb, retinal implant, microchip).
