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

BOSTON, MA – 30/12/2025 – (SeaPRwire) – A new category in consumer wearables is emerging as health technology moves beyond wrists, fingers, and rings. Lumia has unveiled Lumia 2, a smart earring platform designed to continuously monitor blood flow to the head—offering real-time insight into circulation patterns linked to energy levels, focus, and mental clarity. Once confined to clinical research environments, this technology is now entering the consumer market for the first time in the form of everyday jewelry.

Lumia 2 builds on research collaborations with Johns Hopkins, Duke, and Harvard, where the technology was originally developed to support patients with chronic blood flow disorders such as Postural Orthostatic Tachycardia Syndrome (POTS) and Long COVID-19. With its broader launch, Lumia aims to make blood flow awareness accessible to a much wider audience seeking deeper understanding of their daily health and performance.

Designed to be visually indistinguishable from fine jewelry, Lumia 2 supports multiple styles including huggie hoops, studs, and cuffs in gold, silver, and clear finishes. Its patent-pending SwitchBack system allows the smart earring back to attach to standard push-back earrings, while the ear cuff option requires no piercing—expanding accessibility and wearability.

Despite its minimal form factor, Lumia 2 represents nearly six years of engineering refinement. Weighing under one gram and significantly smaller than common wireless earbuds, the device integrates Lumia’s second-generation PreciseLight sensor, processors, battery, and additional health sensors into a single compact module. The ear-based placement enables measurement of physiological signals that are difficult or impossible to capture at the wrist or finger.

In addition to continuous blood flow tracking, Lumia 2 supports a suite of core wearable features including sleep monitoring, temperature trends, menstrual cycle tracking, and readiness metrics. By leveraging the ear’s proximity to both the heart and brain, the platform delivers improved signal consistency while allowing users to continue wearing traditional watches or rings.

According to Lumia co-founder and CEO Daniel Lee, smart earrings represent the next evolution of wearable design. By moving sensing technology into the ear, Lumia is unlocking capabilities that support both everyday wellness insights and longer-term medical research—without compromising aesthetics or comfort.

Alongside the product launch, Lumia announced $7 million in new private investment from J2 Ventures, BonAngels Venture Partners, and angel investors, as well as $5.1 million in government contracts and grants. Total funding to date has reached $17.2 million.

Lumia 2 is engineered for continuous, around-the-clock wear. A new locking mechanism reduces the risk of accidental loss, while a swappable battery pack system enables charging without removing the device. Each battery pack provides approximately five to eight days of use. The Core module is worn on the left ear, while Lumia Earrings are sold as matched pairs.

At the core of Lumia’s value proposition is its focus on blood flow—an often-overlooked metric that can fluctuate even when heart rate and blood pressure appear normal. Clinical validation conducted at leading research institutions has demonstrated a strong correlation between Lumia’s measurements and ultrasound-based blood flow assessments. By visualizing how hydration, posture, diet, movement, and sleep influence circulation, Lumia offers users a new layer of self-awareness tied directly to how they feel throughout the day.

Lumia 2 will support both iOS and Android platforms and will initially launch in the United States and Canada, with additional markets planned. Early access reservations and promotional pricing are available through Lumia’s official website.

Founded in 2020 by former Bose engineers and experienced entrepreneurs, Lumia is headquartered in Boston, Massachusetts. The company operates with guidance from scientific and patient advisory boards and maintains multiple research partnerships focused on improving care for underserved populations. Lumia holds multiple granted and pending patents covering its sensing technologies, modular earring design, miniaturization methods, 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 help users better understand physiological patterns and make informed lifestyle decisions, with diagnostic applications under evaluation for future regulatory submission.
