Basically Wire-Shaped Electrode for Transmittance of Electrophysiological Neurosignals and Method of Manufacture Thereof

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention introduces an improved, wire-shaped electrode designed to record or transmit electrical signals from nerve, muscle, or heart cells, and a method for manufacturing it. The electrode comprises a small-diameter, electrically conductive wire core with an insulating layer, which is locally opened to create specialized contact regions—optionally with microstructures—to enhance connection to individual or few cells and provide better signal quality. Advanced manufacturing techniques like focused ion beam sculpting allow for greater precision and biocompatibility.

Use CasesContent extracted from patent full text and abstract with AI.

• Implantable electrodes for deep brain stimulation (DBS) to treat neurological disorders such as Parkinson’s disease and depression.
• Precision neural recording for brain-computer interfaces or neuroscience research, enabling detection or stimulation at the single-cell level.
• Electrophysiological studies of heart or muscle tissues in live animals, organoids, or tissue cultures.
• Chronic, minimally invasive monitoring of neural activity with reduced immune response or tissue damage.
• High-fidelity stimulation or recording in advanced prosthetics or neuromodulation devices.

BenefitsContent extracted from patent full text and abstract with AI.

• Greater selectivity by targeting single or very few cells, leading to more accurate recordings and stimulations.
• Reduced immune and inflammatory response due to small diameter and biocompatible materials, improving longevity of implants.
• Enhanced signal-to-noise ratio owing to the specially structured contact areas and coatings.
• High flexibility and minimal invasiveness, making implantations and long-term usage safer and more comfortable.
• Customizable design—contact area size, shape, and material—enables tailoring to patient or research needs.
• Manufacturing process with advanced imaging and focused-ion-beam methods ensures precision and reproducibility.
