Wearable devices such as Smart watches and Smart rings They can be bulky, making them difficult to wear 24/7. That’s a gap that smart earring maker Lumia Health hopes to fill with the Lumia 2, which was originally created in collaboration with researchers at Johns Hopkins, Duke, and Harvard to help patients with chronic blood flow disorders.
The company calls the Lumia 2 smart earrings the world’s smallest wearable health care earrings. It’s an earring-like device about the size of a coffee bean, and it has a second-generation PreciseLight sensor and additional processors, battery, and health sensors.
The Lumia 2 earrings were launched on Tuesday Kickstarterearning over $800,000, which is 80 times more than the original goal of $10,000.
What tracks Lumia 2
It weighs less than 1 gram and is five times smaller than AirpodsMiniature biosensor technology allows the Lumia 2 smart earrings to track more than 20 health metrics, including sleep, activity (steps, calories, active minutes), standby, menstrual cycle, temperature, heart rate and variability, blood oxygen (SpO2) and blood flow. It is the latter that inspired the creation of the Lumia Health phone.
“Six years ago, my father fell and broke six of his ribs because not enough blood was getting to his head,” Daniel Lee, co-founder and CEO of Lumia Health, said in a Kickstarter video. “We have to be able to measure blood flow in real time, so we can avoid some of these catastrophic injuries.”
Event tagging is also available, so you can log your activities and behaviors, such as caffeine intake, meditation, and travel.
All this will be available in the accompanying application iOS-And Android-Compatible with iPhone SE (2nd generation) or later, iOS 17 or later and Android 11 or later, with Bluetooth Low Energy 5.0 or later.
Track sleep, blood flow, heart rate, energy and more with Lumia 2.
Different ways to wear it, in one important place
With its three designs – screw-on, hugging hoops, and ear cuffs for those without pierced ears – the Lumia 2 places its sensors right behind your ear. Compared to wearables that rely on the wrist and fingers, this location near the heart and shallow blood vessels in the ear provides, according to Lumia Health, a stronger signal that is less affected by movement, enabling continuous, uninterrupted data.
Although it’s designed to fit most gold, silver, and titanium styles, you can also use the Lumia 2’s SwitchBack technology to connect the device to your existing set of push-back earrings.
Battery life that never ends
Unlike other wearables that require removal to charge, the Lumia 2 uses interchangeable batteries that each last seven days. Once your battery needs charging, simply remove it, swap it out for the fully charged backup and then place the battery that needs to be charged into the charger so it’s ready seven days later.
The use of a swappable battery supports the company’s claim that the Lumia 2 can collect data continuously, especially when you’re asleep, as most people charge their devices during this time.
Every 3 minutes, the Lumia 2 collects blood flow and heart rate metrics, including heart rate. You can also enable Live mode to capture data once per second for a set duration, such as when you exercise or want instant feedback.
There are plans to create a configurable data capture rate that will let you select a higher sampling frequency, such as once per minute, but that will sacrifice battery life.
With replaceable batteries, you never have to wait for your Lumia 2 to charge.
privacy
Data collected by the Lumia 2 is encrypted, anonymized, and access controlled, according to the company, which states in its Kickstarter FAQ that it only shares your data with third-party cloud server providers, like AWS, to help Lumia Health store and serve your data securely.
Or, if you participate in the Data From the People, For the People program, you will allow your data to be added to an aggregated, de-identified set of open source data provided to leading researchers. Lumia Health vets these research partners to ensure they are acting in the best interest of public health and the health conditions the company aims to serve.
When asked how research partners are vetted, a Lumia Health representative did not immediately respond to a request for comment.
Note that the Lumia 2 is not an FDA-cleared medical device, which means it is not designed to diagnose or treat any health condition.

The base price for the Lumia 2 is $249, while collars, cuffs and pins will cost more. All finishes—gold, silver, and titanium—are priced equally.
