Wrist-Powered AI
Wearable Devices Paper Positions Wrist Sensing as 'Intent Layer' for AI, AR, and Robotics.

Wearable Devices Ltd. has published a white paper arguing that a wrist-worn sensor could become the key link between human thought and AI systems, AR headsets, and robots. The paper positions the company's Mudra neural interface as an
The company, listed on Nasdaq under the ticker WLDS, says its sensors pick up electrical signals traveling from the brain to the fingers. Those signals — called Motor Unit Action Potentials, or MUAPs — are captured before a finger even moves. That split-second advantage could let AI agents and AR devices respond to what a person intends to do, not just what they actually do, GlobeNewswire reports.
Wrist Sensors Capture Brain Signals Before Fingers Move
Most AR and AI systems today rely on cameras to track hand gestures. Wearable Devices says cameras fail in low light, eat up computing power, and add friction. Its Mudra wristband uses Surface Nerve Conductance sensors instead. These sensors read the electrical nerve pulses running down the arm, according to GlobeNewswire. The system can detect intent before a physical movement happens.

Large MUAP Model Aims to Build a Rare Data Moat
At the heart of the white paper is a proprietary AI system called the Large MUAP Model, or LMM. The company is building it from years of muscle-signal data collected by Mudra devices. Analysts at Quiver Quantitative note this data could become a hard-to-copy asset — a competitor would need roughly a decade of similar data to match it.
The LMM has uses beyond controlling gadgets. Wearable Devices says it could train robotic hands to move with human-like precision, useful in fields like surgery or household automation. It could also power password-less identity checks, since each person's nerve-signal pattern is unique. The global market for password-less authentication was valued at $21.07 billion in 2024, according to GlobeNewswire.
Revenue Growing But Stock Faces Heavy Financial Pressure
Wearable Devices reported 28.5% revenue growth in its consumer segment for full-year 2025, according to GlobeNewswire. The company held $18.4 million in cash at year-end and raised $24.4 million through equity offerings during the year. CEO Asher Dahan has pointed to that cash as a
Despite those milestones, the company's market cap sat at roughly $4.4 million as of mid-June 2026. AI-driven stock models issue
Privacy Laws and Rival Tech Pose Real Challenges Ahead
The road ahead is not clear. States including Colorado, California, and Connecticut have passed laws treating neural data as sensitive biometric information, according to legal advisories reviewed by research sources. As the LMM grows on MUAP data, regulators may demand strict controls on how that data is stored and sold.
Competition is fierce too. Meta and Apple keep pouring money into camera-based hand tracking that needs no extra hardware. Some researchers also argue that head-mounted EEG devices are better at reading mental states like attention or stress — signals that wrist sensors cannot easily catch. Wearable Devices counters that its wristband is the only practical option for all-day outdoor AR use, where cameras and headsets become impractical, Stock Titan reported.
