Hands-free, voice-led interactions comes to wearables at CES 2026

05 January 2026

Consumer startup Luna has unveiled what it calls the first wearable that provides hands-free, voice-led interactions that are powered by Apple’s Siri AI assistant.

Called Luna Band, the wearable offers voice-led health guidance for personal health information that provides actionable guidance rather than just data, the company said.

The Luna Band’s dynamic logging via voice input allows users to:

  • Log meals
  • Log symptoms if sick or hurt
  • Interpret emotional context
  • Request health guidance

The Luna Band includes an optical sensor array that is paired with a high-fidelity six-axis inertial measurement unit (IMU) that can capture physiological information, circadian fluctuation, emotional stress signatures and other patterns.

“In a market saturated with devices that simply report numbers and do analytics, Luna Band introduces a radically different philosophy: guidance over data,” said a Luna spokesperson.

The core of the guidance is in the LifeOS, a real-time adaptive engine that processes thousands of physiological signals per minute, Luna said. LifeOS identifies:

  • Recovery
  • Stress
  • Circadian alignment
  • Hormonal patterns
