The world’s smallest wellness wearable, smart earrings, just launched on Kickstarter
wearables like smart watches And smart rings Can be heavy, making them difficult to wear 24/7. It’s a gap that smart earring maker Lumia Health hopes to fill with the Lumia 2 device, 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 wellness wearable. It’s a coffee bean-sized earring-back-like device that houses a second-generation PreciseLight sensor, a processor, a battery, and additional health sensors.
Lumia 2 earrings launched on Tuesday kickEarning over $800,000, which is 80 times more than the original goal of $10,000.
What are Lumia 2 tracks?
It weighs less than one gram and is five times smaller AirPodsThe miniature biosensing technology allows the Lumia 2 smart earrings to track over 20 health metrics including sleep, activity (steps, calories and active minutes), readiness, menstrual cycle, temperature, heart rate and heart rate variability, blood oxygen (SpO2) and blood flow. The latter inspired the creation of Lumia Health.
“Six years ago, my father fell and broke six ribs because he didn’t have enough blood flow to his head,” Daniel Lee, co-founder and CEO of Lumia Health, said in a Kickstarter video. “We need to be able to measure blood flow in real time, so we can avoid some of these catastrophic injuries.”
Event tagging is also available, allowing you to log your activities and behaviors, such as caffeine intake, meditation, and travel.
All this will be available in the accompanying app, which is iOS– And Android-Compatible with iPhone SE (2nd generation) or later, iOS 17 or later and Android 11 or later, Bluetooth Low Energy 5.0 or later.
Track sleep, blood flow, heart rate, energy and more with Lumia 2.
Different ways to wear it, an important place
With its three designs – studs, Huggie hoops and ear cuffs for those without pierced ears – the Lumia 2 places its sensors directly behind your ear. According to Lumia Health, compared to wrist- and finger-based wearable devices, this location near the shallow blood vessels of the heart and ear provides a stronger signal that is less affected by movement, enabling continuous, uninterrupted data.
Although it was designed to match most looks in gold, silver and titanium finishes, you can also use the Lumia 2’s Switchback technology to pair the device with an already existing collection of push-back earrings.
Battery life that never ends
Unlike other wearables that need to be removed to charge, the Lumia 2 uses swappable batteries that last up to seven days each. Once your battery needs charging, you simply remove it, replace it with a fully charged backup and then place the battery that needs charging in the charger so it will be ready seven days later.
The use of a swappable battery supports the company’s claim that the Lumia 2 can continuously collect data, especially while you’re sleeping, as most people charge their devices during this time.
Every 3 minutes, the Lumia 2 collects blood flow and heart rate metrics, including HRV. You can also enable Live Mode to capture data once per second for a certain period of time, such as when you’re exercising or want immediate feedback.
There are plans to create a configurable data capture rate that lets you select a higher sampling frequency, such as once per minute, but this will drain battery life.
With swappable batteries, you’ll never have to wait for the Lumia 2 to charge.
confidentiality
The 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 securely store your data and serve you.
Or, if you opt for the Data from the People, for the People program, you will authorize your data to be added to a de-identified, aggregated pool of open-source data provided to top researchers. Lumia Health vets these research partners to ensure that they are acting in the best interests of both public health and the health conditions the company serves.
When a Lumia Health representative was asked how research partners are screened, he did not immediately respond to a request for comment.
Note that the Lumia 2 is not an FDA-approved medical device, meaning it is not designed to diagnose or treat any health conditions.
