Lumia Launches Smart Earrings That Monitor Real-Time Blood Flow, Opening a New Category in Wearable Health

BOSTON, MA – 30/12/2025 – () – The expansion of health technology beyond wrists, fingers, and rings is giving rise to a new category of consumer wearables. Lumia has launched Lumia 2, a smart earring platform that continuously tracks blood flow to the head, delivering real-time insights into circulation patterns that influence energy, focus, and mental clarity. Previously restricted to clinical research settings, this technology is now reaching the consumer market for the first time as everyday jewelry.

Lumia 2 is built upon research partnerships with Johns Hopkins, Duke, and Harvard, where the technology was initially developed to aid patients with chronic blood flow disorders such as Postural Orthostatic Tachycardia Syndrome (POTS) and Long COVID. With its expanded launch, Lumia intends to make blood flow monitoring available to a much broader audience seeking greater insight into their daily health and performance.

Designed to be visually identical to fine jewelry, Lumia 2 accommodates multiple styles including huggie hoops, studs, and cuffs in gold, silver, and clear finishes. Its patent-pending SwitchBack™ system permits the smart earring back to fasten to standard push-back earrings, while the ear cuff alternative requires no piercing—broadening accessibility and wearability.

Despite its diminutive form factor, Lumia 2 embodies nearly six years of engineering advancement. Weighing less than one gram and substantially smaller than typical wireless earbuds, the device incorporates Lumia’s second-generation PreciseLight™ sensor, processors, battery, and supplementary health sensors into a unified compact module. The ear-based positioning facilitates measurement of physiological signals that are difficult or impossible to obtain at the wrist or finger.

Beyond continuous blood flow tracking, Lumia 2 enables a collection of essential wearable functions including sleep monitoring, temperature trend tracking, menstrual cycle monitoring, and readiness assessment. By capitalizing on the ear’s proximity to both the heart and brain, the platform provides enhanced signal reliability while permitting users to retain their conventional watches or rings.

According to Lumia co-founder and CEO Daniel Lee, smart earrings signify the next progression in wearable design. By shifting sensing technology into the ear, Lumia is unlocking functionalities that support both routine wellness insights and extended medical research—without sacrificing aesthetics or comfort.

Concurrent with the product launch, Lumia announced $7 million in fresh private funding from J2 Ventures, BonAngels Venture Partners, and angel investors, along with $5.1 million in government contracts and grants. Aggregate funding to date has attained $17.2 million.

Lumia 2 is designed for continuous, round-the-clock wear. A novel locking mechanism decreases the risk of inadvertent loss, while an interchangeable battery pack system allows for charging without device removal. Each battery pack supplies approximately five to eight days of operation. The Core module is positioned on the left ear, with Lumia Earrings marketed as matched pairs.

At the heart of Lumia’s value proposition lies its concentration on blood flow—an often-neglected metric that can vary even when heart rate and blood pressure seem normal. Clinical validation performed at premier research institutions has demonstrated robust correlation between Lumia’s measurements and ultrasound-based blood flow evaluations. By revealing how hydration, posture, diet, movement, and sleep affect circulation, Lumia delivers users a fresh dimension of self-awareness directly connected to their daily sense of well-being.

Lumia 2 will be compatible with both iOS and Android platforms and will debut initially in the United States and Canada, with further markets slated for later. Early access reservations and promotional pricing are offered through Lumia’s official website.

Founded in 2020 by former Bose engineers and veteran entrepreneurs, Lumia is headquartered in Boston, Massachusetts. The company functions under the guidance of scientific and patient advisory boards and maintains numerous research partnerships dedicated to improving care for underserved populations. Lumia holds multiple granted and pending patents covering its sensing technologies, modular earring design, miniaturization approaches, and battery systems.

Lumia 2 is not an FDA-cleared medical device and is not intended to diagnose, treat, or prevent disease. It is designed to assist users in better comprehending physiological patterns and making knowledgeable lifestyle choices, with diagnostic applications being reviewed for potential future regulatory submission.
