Wireless Brain Implant

The barrier between brains and machines is getting thinner, and the connection denser, and more continuous.

Wireless Brain-Machine-Interfaces (BMIs) aren’t mainstream yet - but this paper is a real Signal. The barrier between brains and machines is getting thinner, and the connection denser, and more continuous (less lab rig, more wearable-adjacent relay + implant). That’s the kind of shift that can quietly unlock higher-resolution, always-on neural I/O over time.

Under the hood, the team describes a mechanically flexible, ultra-thin subdural array with wireless power + data telemetry integrated on a single chip - with a nearby “relay station” handling the off-body link. They report recording from 1024 electrodes simultaneously (selectable regions across the larger array) with a wireless link and inductive power delivery.

This provides upward pressure on the Fidelity dial. As neural capture (and eventually stimulation) becomes more seamless and higher-density, the limiting factor shifts from “can we read anything useful?” to “how faithfully can systems model, predict, and interact with intent / perception in real time?” Definitely not mainstream today - but a meaningful breadcrumb on the path to tighter brain↔machine integration.
