META NEURAL BAND READS WRIST SIGNALS, NOT YOUR MIND

The Meta Neural Band wristband is a Meta made controller that reads the electrical signals your forearm muscles produce when you move your fingers, then turns them into commands for the Meta Ray-Ban Display glasses. Meta owns and sells it. The technology came from CTRL-labs, a startup Facebook agreed to buy in September 2019 in a deal reported at $500 million to $1 billion, and the band reached shoppers on September 30, 2025 inside the $799 Ray-Ban Display bundle.

Surface EMG at the Wrist, Not a Brain Scan

The band uses surface electromyography, or sEMG, which measures muscle activity at the wrist and forearm rather than anything inside the skull. Machine learning decodes those signals into gestures such as a pinch to select or a swipe to scroll, and a haptic buzz confirms the input registered. Meta lists the band as IPX7 water resistant with an 18 hour battery.

The science behind it was published in Nature in July 2025 under the title "A generic non-invasive neuromotor interface for human-computer interaction". Meta's researchers reported that the wristband decoder worked across people without per user training, using data collected from thousands of participants. In closed loop testing the system reached 20.9 words per minute of handwriting, and personalizing the model lifted that by 16 percent.

September 2019: Facebook Buys CTRL-labs

Facebook announced in September 2019 that it would acquire CTRL-labs, a New York neural interface startup co founded by Internet Explorer creator Thomas Reardon, in a deal reported at $500 million to $1 billion. The price was never confirmed by either company. The team folded into Facebook Reality Labs, which is now part of Meta.

Reardon and Patrick Kaifosh are the lead authors on the 2025 Nature paper, so the people who sold the company are the same people whose research now sits under the product. Six years separate the acquisition from a retail box, and the device that shipped is a consumer sEMG band with no brain surgery or electrodes on the scalp involved.

$799 With Glasses, $199 Alone

Meta announced the Neural Band and the Ray-Ban Display at Connect on September 17, 2025, and both went on sale September 30, 2025 at Best Buy, LensCrafters, Sunglass Hut and Ray-Ban stores for $799 together. Meta lists the band at $199 on its own, and reports describe that price as the replacement cost for owners who lose or damage one.

The band is built around the display model. The April 2026 update to the Ray-Ban Display added Reels, navigation and two games, 2048 and GOAT, both played with gestures through the band. Meta's screenless $299 glasses have no lens to point at, and the Ray-Ban Meta line leans on voice, with live translation now at 2.7 seconds.

Connect 2026 Opened the Band to Developers

Meta's developer recap of Connect 2026 on September 23 and 24 says web apps can now read the wearer's context, including wrist motion from the Neural Band, and take text through dictation, handwriting or an on screen keyboard. The Wearables Device Access Toolkit also left preview and reached version 1.0.

The same keynote produced the VR Glasses at 100 grams and the Muse Charm keychain, two more places Meta is moving the interface off the phone. Both run on Muse, the agent Meta launched on September 8, and the band is the input method with the longest research record behind it.
