CES 2025: First Look at a Wearable for Tracking Blood Flow to the Head

Lumia Health this week is giving Consumer Electronics Show (CES) visitors a sneak peek at the world’s first wearable that tracks blood flow to the head. The Lumia wearable is designed to help people better understand and self-manage chronic symptoms of dizziness, brain fog, fatigue, and fainting made worse by standing.*

Since emerging from stealth in 2023, the company completed a 30-day, $560,000 crowdfunding campaign, sold out of pre-order inventory, secured more than $3.6 million in contracts with multiple government agencies, and completed shipments to its Beta customers.

Clinically tested at top institutions like Johns Hopkins, Duke, and Harvard Medical School, Lumia technology has been refined by the world’s top experts in blood flow monitoring. Published at the 2024 American Autonomic Society Conference, the Lumia technology has been clinically shown to correlate strongly with the gold standard—Transcranial Doppler ultrasound—with a Pearson correlation of 0.91 for Carotid Flow Time, a measure of blood flow to the head. At the 2024 Dysautonomia International Conference, Lumia Flow Index was found to correlate better with orthostatic symptoms than traditional heart rate metrics, earning the Patient’s Choice Award.

Hundreds of Lumia Beta testers are already finding immense value in the unprecedented blood flow data, demonstrating exceptional engagement with more than 12 hours of daily wear time and over 40 minutes of daily mobile app use, proving its utility as a self-help tool. The biofeedback helps Lumia members understand the ways that lifestyle factors such as posture, hydration, compression garments, and other daily activities affect blood flow to their head, improving self-awareness and encouraging lifestyle adjustments to avoid exacerbating symptoms.

The Lumia wearable weighs less than 1 gram and is more than five times smaller than Apple Airpods. It tracks blood flow by tapping into a shallow artery in the ear, a branch of the external carotid artery, which runs parallel to the brain’s primary blood supply. This strong arterial signal is crucial to enabling the wearable’s unprecedented cardiac data. Unlike wrist wearables, which suffer from data corruption due to arm movement, the Lumia wearable allows users to track blood flow through various daily living activities. Most users say the wearable is so comfortable and unobtrusive that they completely forget they are wearing it.

“Blood flow to the head is the critical missing vital sign for millions suffering from chronic illnesses affected by dizziness, lightheadedness, brain fog, fatigue, and fainting made worse by standing,” Lumia Health Co-Founder/CEO Daniel Lee said. “After almost five years, we’ve finally unlocked the potential of the ear to track it in a user-friendly wearable, offering insights into these often misunderstood illnesses. While we are focused on chronic brain blood flow illnesses to start, our preliminary research shows that multi-day blood flow monitoring also has the potential to revolutionize many of healthcare’s costliest conditions, from fainting and falling in older adults, to improving in-patient fluid management for sepsis and heart failure.** At CES 2025, we are excited to find partners to help us expand the impact that this groundbreaking technology can have.”

Since its launch, Lumia Health has raised $10.4 million in funding, with additional venture financing and government research contracts. The wearable has undergone various clinical pilot tests at top medical institutions, and has been published in the Journal of the American College of Cardiology and the American Autonomic Society.

Lumia Health is showcasing its blood flow wearable at booth 62047 in Eureka Park at the Venetian Expo (Las Vegas Convention Center) through Jan. 11.

Due to high demand, Lumia wearables are currently still sold out. Sales will re-open Feb. 4th and deliveries are expected to start in March.

Formerly known as STAT Health, Lumia Health is a digital healthtech company improving the quality of life for people living with chronic cardiovascular and neurological diseases, starting with chronic illnesses experiencing drops in blood flow upon standing. Lumia Health accomplishes this through its hardware platform—the ear wearable—and targeted software programs built atop its longitudinal cardiac data. Founded in 2020, Lumia Health is backed by venture capital firms, government grants, and a growing community of early adopters. The founders, Daniel Lee and Paul Jin, previously ran Bose’s Health Product Innovation Group, and Lee invented Bose sleepbuds.
