Smart overview of the Invention

The neural interface device comprises a system that includes a controller, a set of scaffolds, and a tissue interface, with optional integration of an external device. It can function as an intracortical brain-computer interface placed on the brain's surface. The device is designed to transmit information to and from a user's brain, enabling functions such as motor control, speech decoding, sensory restoration, and augmentation.

Examples

The system can be embedded in-situ on the brain's surface and includes components like a controller and stacked scaffolds with engineered cells seeded between them. These scaffolds are arranged in layers with spacers, and each contains excitation elements (e.g., μLEDs) and sensor elements (e.g., electrodes). Engineered cells may include optogenetically modified neurons, capable of interacting with native brain tissue through light stimulation or signal detection. These cells can be retained in a hydrogel, allowing axons and dendrites to interface with the brain.

Technical Advantages

  • Scalability: The system offers a high channel count without increasing brain damage, unlike conventional interfaces. It uses stacked scaffolds with engineered cells to minimize impact on native neurons.
  • Sensory Restoration: It can restore or augment senses, treat neurological disorders, and perform motor control by recording and stimulating engineered cells that interface with brain neurons.
  • Efficient Design: The device eliminates the need for large electrode systems by using scalable display implants with high resolution and fewer hermetic feedthroughs.

System Components

The system includes a controller, scaffolds, and a tissue interface, optionally working with external devices like computing systems or user interfaces. These components can process data, display outputs, and interact with users. The computing system may include CPUs, GPUs, TPUs, or cloud servers for processing tasks.

Application

The neural interface device is designed to be used with various tissues of interest, primarily the brain but also potentially including the spinal cord or other body regions. It can be implanted at specific locations such as the brain surface or within the skull. The system is suitable for humans and animals alike, offering broad applicability in interfacing directly with biological tissues.
