If you’ve ever wondered what comes after watches and rings, the answer is finally here and it looks nothing like you would ever expect.
Meet Lumia 2, the smart earrings that have everyone’s attention for being the smallest and most interesting wearable ever. The Boston-based engineering firm, Lumai, took six years to build these smart earrings and honestly, it shows.
Here’s more on smart earrings, their accuracy, benefits and how Lumia might be the most discreet wearable ever.
What are Smart Earrings and How Ears Became the Prime Real Estate for Health Data
Smart earrings are a new class of wearable technology that look and feel like regular earrings, but quietly track your health data throughout the day and night. They look like your regular earrings from the front- be it in the form of hoops, studs, or cuffs, the back is where the sensors are stored.
The earring back or clasp is where tiny sensors, processors and batteries are tucked away. They don’t buzz at your wrist or light up on your finger; they simply collect data in the background while blending seamlessly in your jewellery box.
Why have ears become the new data collection point? It is because of the placement of these sensors. The advantage here is that the sensors sit close to the brain and heart with a stable blood flow and minimal motion (unlike wrists and fingers).
Blood Flow: the Biomarker We’ve Been Missing
Your heart rate may look normal, and so would your blood pressure. But your blood flow could answer questions like:
Why do I feel lightheaded when I stand up too fast?
Why do I get brain fog after lunch?
Why did a meeting suddenly tank my energy?
Lumia 2 uses infrared light to measure arterial blood flow in the shallow ear artery, the one closest to your brain. Blood flow changes constantly based on our hydration levels, posture, carbs and caffeine, sleep quality, stress, room temperature and exercise timing. Lumia makes it possible to determine the impact of these factors on our blood flow outside of a clinical setting.
Lumia 2 is not FDA cleared because it does not claim to diagnose, treat or prevent any disease; therefore, it does not fall into a “medical category”.
How Lumia is Creating the Smallest and Smartest Wearable
The back of the earring, called Lumia Core, is five times smaller than the AirPods and weighs less than 1 gram, according to the company. Honestly, I have seen lentils bigger than that.
But Lumis didn’t enter the market as a consumer product. Their earliest orototypes were developed with research at Harvard, Duke and Johns Hopkins, mainly for patients with conditions where blood flow irregularities caused dizziness, fatigue and cognitive crashes like POTS or Long COVID.
Lumia realised something bigger- even people without any medical diagnoses and having “normal vitals” were not feeling normal all the time. Enter- Lumia 2, still grounded in clinical engineering but made for anyone who is curious about how their body functions.
The company has secured $7 million in new investment and $5.1 million in government contracts, bringing its total funding to $17.2 million. These are not the kind of numbers you get for a gimmicky product.
Features
Alongside tracking blood flow, Lumia 2 monitors:
- Sleep stages
- Resting Heart Rate (RHR)
- Heart Rate Variability (HRV)
- Skin temperature
- Menstrual cycle tracking
- Daily readiness
- Hydration-related changes
- Stress
As for the charging, the Lumia Core is swapped with another pack so that you don’t have to remove the earring. Each pack lasts 5-8 days.
Honestly? More wearables should work like this.
Accuracy
Because of the positioning of the sensor, it sits closer to the major arteries and doesn’t move as much as your fingers or wrists, making the readings taken by smart earrings more stable and reliable.
Infrared lights also penetrate deeper than the green LEDs used in watches and smart rings, making the signal quality better, especially during sleep, stress, or quick postural changes.
Benefits
- Smart earrings are discreet
- Stylish
- Lightweight and comfortable to wear 24/7
- They don’t interfere with typing ot workouts
- You get the same (and even more) metrics that you get from watches and rings
- Blood flow pattern helps explain energy dips and brain fog.
Wrap Up
Smart earrings are breaking all the rules in wearable tech and how we integrate them into our day-to-day lives. They don’t scream “health tracker,” and they live close to the places where physiology speaks the loudest.
These aren’t gimmicky. They are the tech accessory we didn’t even know we deserved. The one that blends science with jewellery and self-understanding into a single gram of metal.
This is a gadget that is quietly rewriting the rules.
