Nuna Pendant: The World’s First AI Emotion-Tracking Necklace
ThingX Technology has developed the “Nuna Pendant” – an innovative AI-powered necklace as the world’s first wearable designed specifically to track emotions.
It supports emotional health by translating body signals, voice, and environmental cues into actionable emotional insights using cutting-edge embedded AI.
What Makes Nuna “A First”?
The Nuna Pendant stands out as the first-ever wearable combining mmWave radar with embedded, multimodal AI that senses both internal states (like heartbeat) and external context (like voice tone and environment)—all processed privately on-device. There’s nothing else like it on the market.
Key Features
Multimodal AI Sensing: The pendant uses millimeter-wave radar to monitor heartbeats, breathing, and tiny physical movements, along with voice analysis for tone, pace, and energy merging multiple data streams into a clear emotional picture.
All processing happens on the device itself, ensuring privacy.
Emotion Tracking & Auto Journaling (“Moments”): Nuna logs your emotional state continuously and creates an automatic “emotional diary” of your day called Moments so you can see patterns and triggers over time.
Mindfulness Support & Haptic Cueing: The pendant offers guided breathing and meditation prompts, plus a gentle vibration feature called NunaPulse to offer calming reminders when you need them.
Emotion Reports & Visual Insights: Through the companion app, Nuna provides simple visual summaries like mood charts, speaking patterns, and silent versus emotional moments to help you reflect and respond to your feelings.
Privacy-First Design: No raw audio is ever stored or sent. There are no wake words or continuous recording.
All sensing and analysis happen locally on the device, respecting your personal space and data.
Elegant, Jewelry-Like Aesthetics: Designed as a beautiful piece of jewelry available in Silver with inspiration drawn from natural elements.
It’s meant to feel like a lovely accessory, not just a gadget.
Background & Development
Nuna Pendant originally known as PieX (Personal Index) during research and prototyping stages, the device is the result of 20 years of multimodal sensing research.
ThingX refined the concept through two years of design and user studies to ensure the pendant would be both emotionally intelligent and delightfully human-centered to serve as a gentle mirror for your feelings.
