Scalable batch fabrication of ultrathin flexible neural probes

Index

Abstract

This paper presents a novel scalable batch fabrication approach for ultrathin and flexible neural probes. The probes consist of a silk-parylene bilayer, where the biodegradable silk layer acts as a temporary stiffener for insertion, enabling the use of ultrathin parylene-based flexible devices. This method allows for control over probe design and has shown successful ex vivo insertion with high-fidelity recordings of epileptic seizures and single-unit action potentials in mouse brain slices.
