Emteq Labs is a UK-headquartered deep-tech company developing smart eyewear that uses patented optical sensors and machine learning to measure facial muscle activity, emotional responses, and behavioral patterns in real-world settings. Founded in 2015 by facial musculature surgeon Dr. Charles Nduka, the company has built the first wearable platform for continuous, non-contact facial sensing outside the laboratory.

The company's proprietary OCO (Optomyography) sensors detect high-resolution facial skin movement in three dimensions at up to 6,000 samples per second, without requiring skin contact or cameras. Integrated with inertial measurement units, heart rate monitoring, and an outward-facing camera, the system tracks facial expressions, eating behavior, posture, physical activity, and emotional valence. Companion machine learning models analyze multimodal data streams to generate behavioral and affective insights.

Emteq's Sense eyewear platform targets health and wellness applications including dietary monitoring (automatic food logging and bite detection), mental health screening (depression detection validated in peer-reviewed studies), and emotion analytics for research and commercial settings. The company collaborates with universities including Stanford, Northeastern, and Cambridge, and holds 27 patents. It is exploring licensing of its sensing technology to major smart glasses manufacturers for integration into next-generation AR/VR devices.
