This Brain-Computer Interface Is So Small It Fits Between the Follicles of Your Hair

Summary
A new neural interface small enough to be attached between a person’s hair follicles could provide a useful, non-invasive way of controlling devices.
Existing brain-computer interfaces (BCIs) are often impractical and hamper a user’s movement, but the new device promises to be more adaptable for everyday use.
The mini interface is just 0.04in wide and uses tiny microneedles to attach to the scalp and penetrate the outer layer of dead skin to acquire better signals.
The team who developed it were able to demonstrate its uses by using it to control augmented reality video calls, with the interface remaining stable for up to 12 hours after implantation.
It could also be used as a health monitor, providing a constant stream of biofeedback to wearable devices.
