Abstract
In one embodiment, a neural interface system includes an implantable neural probe having a flexible substrate, electrodes that extend from the substrate that are adapted to contact neural tissue of the brain, a signal processing circuit configured to process neural signals collected with the electrodes, and a wireless transmission circuit configured to wirelessly transmit the processed neural signals, and a backend computing device configured to wirelessly receive the processed neural signals, to process the received signals to reconstruct the collected neural signals, and to analyze the collected neural signals.
Claims26
A neural interface system comprising:
- an implantable neural probe comprising:
- a flexible substrate comprising a body and an integral compliant arm that extends outward from the body, wherein the compliant arm can be bent substantially 90 degrees relative to the substrate body to enable electrode embedding,
- electrodes that extend from the compliant arm in a direction parallel to the arm that are adapted to be embedded in neural tissue of the brain,
- a signal processing circuit formed or mounted on the flexible substrate, the signal processing circuit being configured to process neural signals collected with the electrodes, and
- a wireless transmission circuit formed or mounted on the flexible substrate, the wireless transmission circuit being configured to wirelessly transmit the processed neural signals;
- and
- a backend computing device configured to wirelessly receive the processed neural signals, to process the received signals to reconstruct the collected neural signals, and to analyze the collected neural signals.
An implantable neural probe adapted for implantation beneath the scalp of a patient, the probe comprising:
- a flexible substrate having a body and an integral compliant arm that extends out from the body;
- electrodes that extend from the compliant arm in a direction parallel to the arm that are adapted to contact neural tissue of the brain;
- a signal processing circuit formed or mounted on the flexible substrate, the signal processing circuit being configured to process original neural signals collected with the electrodes;
- a wireless transmission circuit formed or mounted on the flexible substrate, the wireless transmission circuit being configured to wirelessly transmit the processed neural signals to a backend computing device;
- and
- an internal power source that supplies power to the signal processing and wireless transmission circuits;
- wherein the compliant arm can be bent to an approximately 90 degree angle relative to the substrate body to enable embedding of the electrodes into the neural tissue.
