New in-ear bioelectronic device could revolutionize brain-computer interface system

Key points from article :

A new in-ear bioelectronic called SpiralE may be the next step toward seamless brain-computer interfaces.

It is a small electronic device made of a flexible polymer that transmits electronic signals from the user to a computer.

It was developed with a comfortable, removable form factor with all the functionality of bulkier or more invasive devices.

Electrothermal components, wiring, adhesion, and so on, all packed in a memory polymer that molds to the ear canal of the user, maximizing comfort and stability.

It is entirely self-contained, and can be removed by the user in seconds and just as easily be reinserted.

Spiral design allows for unimpeded hearing while in use; the user continue to hear unobstructed at cocktail party noise levels.

Auditory tests confirm that the device itself continues to function with 84% accuracy in high volume environments.

Only need for replacement would be regular wear and tear from daily use.

The compact and simple design of SpiralE will keep production costs reasonably low.

It has the potential to revolutionize regenerative medicine, including applications in motor and language rehabilitation and assistance.

Study led by Zhouheng Wang from Tsinghua University, published in Nature.
