Developing the right material for brain implants

30-May-2018

Key points from article :

The Verge interview Christopher Bettinger from Carnegie Mellon University.

Devices use electrons to pass information.

Neurons use ions like sodium and potassium.

Small movements of the probe can damage the tissue over time.

Damage doesn't cause disease but does reduce life of the device.

Polymer gels can bend and stretch so may last longer.

Could attach devices to other places, e.g. spine or bladder.

The study was published in the Advanced Functional Materials journal.

Silicon-based brain implants still need a lot of improvement but will work for now
