Unlocking Performance: The Power of Light

At Lumen Fit, we harness the revolutionary potential of light-based technology to provide you with the most accurate and insightful fitness data available.

The Science of Light

How Photoplethysmography (PPG) Works

Our core technology is built upon advanced Photoplethysmography (PPG), a simple yet powerful optical technique that detects blood volume changes in the microvascular bed of tissue. Tiny LED lights penetrate your skin, and a photodetector measures the amount of light reflected or transmitted. As blood flows and pulses, the light absorption changes, creating a waveform that directly corresponds to your heart's activity.

Unlike traditional methods, Lumen Fit's multi-wavelength PPG sensors provide a richer data set, allowing for unparalleled accuracy in heart rate, heart rate variability, and even blood oxygen saturation (SpO2) measurements.

Many traditional wrist-based trackers struggle with accuracy during intense workouts due to motion artifacts. Lumen Fit’s proprietary algorithms and strategically placed sensors within our smart apparel drastically reduce this interference. Our light-based sensors provide continuous, precise data, even during high-intensity interval training, running, or weightlifting, giving you real-time insights you can trust.

Superior Motion Artifact Rejection: Algorithms filter out noise from movement.
Multi-site Measurement: Optimal sensor placement for consistent data.
Clinical Grade Precision: Data comparable to medical-grade devices for key metrics.

Smart Apparel: Engineering for Performance

Our smart athletic apparel integrates ultra-thin, flexible optical sensors directly into performance fabrics. These sensors are designed to be imperceptible, durable, and resistant to sweat and environmental factors. The seamless integration ensures optimal skin contact for reliable data capture without compromising comfort or athletic performance.

From moisture-wicking and breathable materials to ergonomic sensor placement, every aspect of our apparel is engineered to enhance your training and recovery.
