Multielectrode Microprobes for Deep-Brain Stimulation Fabricated using a Novel 3-D Shaping Electroplating Process
Year: 2002
Type: conference-paper
Abstract: This paper describes a novel 22-mm-long multi-channel microelectrode suitable for deep-brain stimulation in rodents.The platinum electrodes and conducting interconnects are insulated by silicon nitride and the mechanical support is provided by a 3-D electroplated biocompatible metallic structure.The shape of the probe has been designed to provide sufficient mechanical stiffness for accurate targeting of deep-brain regions while minimizing tissue damage.The probe thickness and width are smoothly tapered from the 200-µm-wide and 150-µm-thick shank to the 10-µm-thick probe tip.The electrical and mechanical properties of the electrode array have been tested and show an impedance of 4.5 kΩ at 10 kHz.
