As I made various gestures, the display behind me showed what I thought was a live representation of neural signals flowing through my wrist and to my fingertips. Repeated actions would seem to yield similar patterns on the screen and, when a rep from the company moved my finger, I saw no signals to indicate that it was actually reading the commands I was sending my finger just a few seconds earlier.
Mudra Link representatives describe its sensors as “Surface Nerve Conducting (SNC)”, and the description of how it works sounds very similar to
, which Meta describes as using sEMG (Surface electromyography). Both devices sense the electrical signals passing through your wrist to the muscles in your hand, your brain telling your fingers to move, in order to detect the positions and movements of your fingers without the need for optical hand tracking.
Representatives also pitched the idea of a pair of the wristbands, one each for mouse and keyboard, but I didn’t test this myself. Although bands such as TapXR can also provide this feature, I find it fascinating to think about the concept of dual-bands being refined to work with other input devices. This could lead to powerful effects that give haptic feedback when specific gestures are used to send commands to the devices around you. As I have tried many input systems like the current open-air hand tracking system, they only recognize one pinch gesture that indicates when fingertips are in contact. Mudra Link representatives, on the other hand, claim that their product can also measure the pressure between fingers. The gauge filled as I squeezed together my fingers, pointing to potential possibilities. Meta’s neural wristbandAt CES 2025, a representative wore TCL’s RayNeo X3 Pro AR glasses while showing the basic concept for controlling menus with the wristband.
The price for the Mudra Link wristband is $199 as of this writing, with plans to ship in the coming weeks.

Compatibility
The Mudra Link’s cross-platform compatibility ensures that you can enjoy the benefits of gesture control regardless of your preferred device ecosystem.
Wristbands like Mudra Link are an exciting development in wearable technology and hold a lot of promise for robust input within glasses and headsets. With precise control, pressure detection features, and potential wide compatibility with AR and XR devices, the Mudra Link wristband and
could play a crucial role in the future of how we interact with our augmentations, virtual environments, and all the other devices around us.

While my demo was exciting and showed the potential for this tech, it wasn’t perfect. It was difficult to test the device in real life because it used Bluetooth, which caused interference. The limited demo at CES did not allow us to determine if this product would work for everyday tasks. We’re looking forward to getting a unit in our studios to test further. Once we have, we will be able share more information about potential uses and reliability. Until then, I look forward to hearing more from Mudra Link and about other wearable XR technologies.similar upcoming devices
