material and mechanical properties of stainless steel to design miniaturized biomedical devices such as high channel density neural probes with micron-scale features on stainless steel. Our devices are robust, reusable, customizable, and can be produced at scale.”
Breakthrough for1 brain disorders This breakthrough is particularly important, both as a diagnostic tool and also as an intervention tool for patients with brain disorders such as epilepsy, Parkinson’ s Disease, and schizophrenia. Zabir Ahmed, who worked on this project as part of his Ph. D. thesis at Carnegie Mellon University, is excited about the great potential of this platform technology, even beyond neural interfacing.“ Beyond creating robust stainless steel neural probes for clinical use, I’ m excited that this work introduces a novel planar microfabrication process directly on steel,” says Ahmed.“ This manufacturing process could lead to a new class of resilient devices that integrate multiple functionalities on steel, which can be useful for a wide range of applications.” In addition to microfabrication on stainless steel, the team has also optimized post-fabrication processing and packaging.“ Designed for seamless integration, our packaging method works effortlessly with commercial stimulation and recording systems— making it easy for researchers and medical professionals to readily adopt our stainless steel devices,” says Ibrahim Kimukin, a research scientist in Chamanzar’ s lab“ This research represents a step-change in how we can interface with the brain, achieving high-resolution recording and stimulation using robust, clinically
Customizable stainless steel neural probes are microfabricated using a multilayer process, which enables high-density electrode integration.
Steeltrodes provide much higher channel count and density, yet can be mass produced at a fraction of the cost of traditional laminar probes.
scalable materials,” said Vishal Jain, a research scientist in Chamanzar’ s lab.“ I’ m thrilled to have contributed to the design and validation of this technology, which bridges the gap between research-grade precision and real-world translational potential.”
Assisting research Outside of the clinic, the probes also fill an important gap for neuroscience research. According to co-author Tobias Teichert, associate professor of psychiatry and bioengineering at the University of Pittsburgh, hand-made laminar electrodes have much lower density and can cost significantly higher.“ The design of these steeltrodes is an amazing advancement because they provide much higher channel count and density, yet at the same time, they can be mass produced at a fraction of the cost,” says Teichert. In the future, the team hopes that neurosurgeons will be able to use multiple stainless steel probes on a patient in order to generate a more comprehensive recording of brain activity.“ Using steeltrodes, one day we will be able to record neural activity across multiple areas of the brain with high resolution and minimal damage to the brain tissue,” explains Chamanzar.“ This crosshatch of neural recordings will change the diagnosis and treatment of brain diseases.”
