| Abstract Scope |
Microelectrode arrays are used for recording electrophysiological activities from brain tissue which helps to understand neural activities and to diagnose and monitor neural diseases. Chronic recording from the same neuron over a period is possible with a biocompatible neural implant. Implantable neural probes with 3D gold electrodes have potential to record neural signals with minimum infection and inflammation to the brain tissue. To penetrate the brain tissue and record from it, 3D gold electrodes need to have mechanical strength and electrical reliability. In this work, we used Aerosol Jet 3D nanoprinting to demonstrate the fabrication of gold micropillars with aspect ratios of up to 10:1 and studied for mechanical and microstructural characteristics. To evaluate the application of the micropillars, a brain computer interface (BCI) was designed and fabricated with the micropillars as microelectrodes. We successfully demonstrated the capability of the BCI by recording neural signals from rat spinal cords. |
