High Density Silicon Probes with Flexible Cables for Neural Prostheses (2003-present)

An important common goal, although futuristic, is to achieve cortex prostheses using implanted probes to control robotics by pure thoughts. The first beneficiaries are likely to be patients with spinal-cord injuries, peripheral nerve disease, or amyotrophic lateral sclerosis.

We are developing a new parylene-enabled silicon neural probe electrode sensor for a neural prostheses direct brain interface system. We successfully combined parylene coating/etching process with silicon neural probes dry etching process to build parylene on silicon probes as insulating and protecting material, and at the same time to monolithically integrate flexible parylene cables with silicon neural probes. The new neural probes were shown to have better biocompatibility, lower stress, and better flexibility to be made to high-density 3-Dimensional array and to be used for chronic neural signal recording implantation. Right now, we are aiming for high density probe array with one hundred electrode sensors for clinical trials.

 

  

 

 

 

MEMS Movable Neural Probes (2003-present)

Recent studies using neural probes indicate that it is highly desirable for the probes to have moving capability so that it can track a specific neuron in the brain, because live neurons do move around. However, for brain use, the movable neural probes need to be powerful (to penetrate brain tissue), high density, low power, bidirectional and latchable (without power). We are now developing a novel electrolysis-based parylene balloon actuator for movable probes.
